welcome hunger

first world nations have first world problems.  instead of fighting hunger, we fight fat.

one of the habits i wish to develop this year is to minimize my gut (and weight).

let me rewind to just before the beginning of august 2014.  prior to august, it was routine for me to "begin my weekend" by stopping at the store for a gallon or half gallon of ice cream.  i still remember one of my favorite kinds of ice cream: premium select michigan cherry cobbler.  if i bought it on a friday, it would be gone before sunday.

time and time again, my family would say i ate too much ice cream.  so while driving home from our vacation in august 2014, i decided to quit - cold turkey.  today, it's been 150 days since i've eaten any ice cream.

i'd like to say i've lost of ton of weight since i've dropped creamy dreamy from my diet.  sadly, i've only gone down a couple of pounds.

what has worked for me is intermittent fasting.  one of the obstacles of IF is dealing with hunger pangs.  hunger pangs are funny.  if feels like the world is going to end, but i know darn well that i won't die if i don't eat.  as i thought about how to deal with the pangs, a thought came to me.

"welcome hunger like a dear friend: with a warm cup."

hunger is a friend and should never be dismissed with saltiness or anything.  rather, it should be greeted and welcomed with a warm cup of herbal tea or simply warm water and lemon.

be mindful of hunger's presence, but don't dismiss him in favor of false friends who do no good.

minimize daily

the aim of daily minimalist is to document my journey of minimizing the bad and focusing on the good: in health and habits and possessions.  i hope that i can offer advice to those to are starting or who are already on this journey.

one of my smaller goals and habits i want to develop for 2015 is to maximize garbage day.

every space around your home can be de-cluttered and organized a little bit each day.  granted, some spaces need to be managed with a "mini project" that may take an hour or more.  but as you clean and organize day by day, find things to toss.

a lot of people will be taking down holiday decorations this week.  this is a great time to maximize your garbage day.  most of our holiday decorations are stowed in the master bedroom closet.  after i took out the empty boxes, i took advantage of the empty space and minimized my wardrobe.

any shirt or set of pants i had not worn for several months, i dumped in a big garbage bag (to be donated to a thrift store).

i took took out several boxes sitting on my shelf; went through them.  most of the contents were old CDs and DVDs.  all the CDs had already been ripped to mp3s; those that were not ripped to my digital library were later ripped that day.  the CDs were then tossed.

another box was full of old pictures.  the plan is to scan every picture we have and then get rid of the physical pictures.  i estimate about a quarter of my pictures have been scanned and digitized.

another box was full of our children's old school works: essays, art, poems, etc.  these too will be scanned or digitally photographed before being tossed.  most of our kids's work that is worth digitizing, has already been digitized.  this box was a leftover from a previous digitization project.

the master bedroom closet can take some time to minimize.  take it in chunks.  minimize half of it one day and then tackle the other half another day.

but back to the point - minimize daily; take full advantage of garbage day.  yes, you'll need to have a few minimization projects, but there still is a lot you can do on a daily basis.

when watching, watch. when eating, eat.

i took my two older kids to the movie the other day.  part of the experience for them is getting to eat unhealthy "food"

between the two kids, they had a big bag of greasy, salty popcorn along with a full-sized bag of mega peanut m&ms.

when they offered some to me, i passed.  however, about 3/4ths though the movie, i wanted to taste a couple of peanut m&ms.  after asking my daughter to pass the bag, she said they were all gone.  i was shocked!  she said her brother ate most of them!

after the movie, my son was sitting in the back seat of the truck and was complaining about a headache.  my daughter and i explained to him that this was because he ate a whole bag of sugar.  movies and junk food don't mix well for some.

as i thought of this on my walk this morning, i was reminded of the zen proverb "when walking, walk.  when eating, eat."

the point of this proverb and this story about my son is this: we need to focus on what we are supposed to be doing.

minimalism is nothing more than focus.

Mind of the Meditator by Ricard, Lutz and Davidson

Saving this article to read and reference in the future.  This was featured in the November 2014 Scientific American magazine.

When the Society for Neuroscience asked Tenzin Gyatso, the 14th dalai lama (the leader of Tibetan Buddhism), to address its annual meeting in Washington, D.C.,in 2005, a few hundred members among the nearly 35,000 or so attending the meeting petitioned to have the invitation rescinded. A religious leader, they felt, had no place at a scientific meeting. But this particular leader turned out to have a provocative and ultimately productive question to pose to the gathering. “What relation,” he asked, “could there be between Buddhism, an ancient Indian philosophical and spiritual tradition, and modern science?”

The Dalai Lama, putting action before rhetoric, had already started trying to find answers to his own question. Back in the 1980s, he had sparked a dialogue about science and Buddhism, which led to the creation of the Mind & Life Institute, dedicated to studying contemplative science. In 2000 he brought new focus to this endeavor: he launched the sub-discipline of “contemplative neuroscience” by inviting scientists to study the brain activity of expert Buddhist meditators—defined as having more than 10,000 hours of practice.

For nearly 15 years more than 100 monastics and lay practitioners of Buddhism and a large number of beginning meditators have participated in scientific experiments at the University of Wisconsin–Madison and at least 19 other universities. The article you are reading, in fact, is the product of a collaboration between two neuroscientists and a Buddhist monk who originally trained as a cell biologist.

A comparison of the brain scans of meditators with tens of thousands of hours of practice with those of neophytes and non-meditators has started to explain why this set of techniques for training the mind holds great potential for supplying cognitive and emotional benefits. The goals of meditation, in fact, overlap with many of the objectives of clinical psychology, psychiatry, preventive medicine and education. As suggested by the growing compendium of research, meditation may be effective in treating depression and chronic pain and in cultivating a sense of overall well-being.

The discovery of meditation’s benefits coincides with recent neuroscientific findings showing that the adult brain can still be deeply transformed through experience. These studies showthat when we learn how to juggle or play a musical instrument, the brain undergoes changes through a process called neuroplasticity. A brain region that controls the movement of a violinist’s fingers becomes progressively larger with mastery of the instrument. A similar process appears to happen when we meditate. Nothing changes in the surrounding environment, but the meditator regulates mental states to achieve a form of inner enrichment, an experience that affects brain functioning and its physical structure. The evidence amassed from this research has begun to how that meditation can rewire brain circuits to produce salutary effects not just on the mind and the brain but on the entire body.

WHAT IS MEDITATION?
Meditation has roots in the contemplative practices of nearly every major religion. The prevalence of meditation in the media has given the word various meanings. We will refer to meditation as the cultivation of basic human qualities, such as a more stable and clear mind, emotional balance, a sense of caring mindfulness, even love and compassion—qualities that remain latent as long as one does not make an effort to develop them. It is also a process of familiarization with a more serene and flexible way of being.

In principle, meditation is relatively simple and can be done anywhere. No equipment or workout attire is needed. The meditator begins by assuming a comfortable physical posture, neither too tense nor too lax, and by wishing for self-transformation and a desire for others’ well-being and for the alleviation of their suffering. Later the practitioner must stabilize the mind, which is too often disorderly—and occupied by a stream of inner chatter. Mastering the mind requires freeing it from automatic mental conditioning and inner confusion.

We will examine here what happens in the brain during three common types of meditation developed through Buddhism and now practiced in secular programs in hospitals and schools throughout the world. The first one, focused-attention meditation, aims to tame and center the mind in the present moment while developing the capacity to remain vigilant to distractions. The second one, mindfulness, or open-monitoring meditation, tries to cultivate a less emotionally reactive awareness to emotions, thoughts and sensations occurring in the present moment to prevent them from spiraling out of control and creating mental distress. In mindfulness, the meditator remains attentive, moment by moment, to any experience without focusing on anything specific. Finally, another type of practice is known in Buddhist tradition as compassion and loving kindness and fosters an altruistic perspective toward others.

UNDER THE SCANNER
Neuroscientists have now begun to probe what happens inside the brain during the various types of meditation. Wendy Hasenkamp, then at Emory University, and her colleagues used brain imaging to identify the neural networks activated by focused-attention meditation. In the scanner, the participants trained their attention on the sensation produced by breathing. Typically during this form of meditation, the mind wanders from an object, and the meditator must recognize this and then restore attention to the gradual rhythm of the inhaling and exhaling. In this study, the meditator had to signal mind wandering by pressing a button. Researchers identified four phases of a cognitive cycle: an episode of mind wandering, a moment of becoming aware of the distraction, a phase of reorienting attention and a resumption of focused attention.

Each of the four phases involves particular brain networks. The first part of the cycle, when a distraction occurs, increases activity in the wide-ranging default-mode network (DMN). This network includes areas of the medial prefrontal cortex, the posterior cingulate cortex, the precuneus, the inferior parietal lobe and the lateral temporal cortex. The DMN is known to become activated during mind wandering and to play a general role in building and updating internal models of the world based on long-term memories about the self or others.

The second phase, becoming aware of a distraction, occurs in other brain areas such as the anterior insula and the anterior cingulate cortex, regions of what is called the salience network. This network regulates subjectively perceived feelings, which might, for instance, lead to being distracted during a task. The salience network is thought to play a key role in detecting novel events and in switching activity during meditation among assemblies of neurons that make up the brain’s large-scale networks. It may shift attention away from the default-mode network, for instance.

The third phase engages additional areas—among them the dorsolateral prefrontal cortex and the lateral inferior parietal lobe— at take back” one’s attention by detaching it from any distracting stimulus. Finally, in the fourth and last phase, the dorsolateral prefrontal cortex continues to retain a high level of activity, as the meditator’s attention remains directed toward an object such as he breath.

In our laboratory at Wisconsin, we further observed different patterns of activity depending on a practitioner’s level of experience. Veteran meditators with more than 10,000 hours of practice showed more activity in these attention-related brain regions compared with novices. Paradoxically, the most experienced meditators demonstrated less activation than the ones without as much experience. Advanced meditators appear to acquire a level of skill that enables them to achieve a focused state of mind with less effort. These effects resemble the skill of expert musicians and athletes capable of immersing themselves in the “flow” of their performances with a minimal sense of effortful control.

To study the impact of focused-attention meditation, we also studied its volunteers before and after a three-month retreat with intensive meditation exercises for at least eight hours a day. They received headphones that broadcast sounds at a given frequency, occasionally mixed with slightly higher-pitched sounds. They had to focus on the sounds played in one ear for 10 minutes and react to periodically interspersed high-pitched tones. After the retreat, we found that meditators, compared with a non meditating control group, showed less trial-to-trial variation in their reaction times on this highly repetitive task, which lent itself easily to distractions. The result suggested that the meditators had an enhanced capacity to remain vigilant. The brain’s electrical responses to high-pitched tones remained more stable at the second session only for the meditators.

STREAM OF CONSCIOUSNESS
The Second type of well-studied meditation also involves another form of attention. Mindfulness, or open-monitoring meditation, requires the meditator to take note of every sight or sound and track internal bodily sensations and inner self-talk. The person stays aware of what is happening without becoming overly preoccupied with any single perception or thought, returning to this detached focus each time the mind strays. As awareness of what is happening in one’s surroundings grows, normal daily irritants—an angry colleague at work, a worried child at home—become less disruptive, and a sense of psychological well-being develops.

With Heleen Slagter, then in our group at Wisconsin, we sought to learn about the influence of this form of training on mental functioning by measuring the participants’ capacity to detect rapidly presented visual stimuli—a means to measure mindfulness meditation, which is also sometimes called nonreactive awareness. To perform this experiment, we used a task in which the participants had to detect two numbers presented on a screen rapidly, amid a succession of letters. If the second number appears about 300 milliseconds after the first one, subjects often do not see the second, a phenomenon known as attentional blink.

If the second number appears after a delay of 600 milliseconds, it can be detected without difficulty. The attentional blink Reflects the limits of the brain’s ability to process two stimuli presented to the observer at close intervals. When too much of the brain’s attention is devoted to processing the first number, the second number cannot always be detected, although the observer usually can see it on some of the trials. We hypothesized that mindfulness training could reduce the propensity to “get stuck,” or absorbed by seeing the first number. Mindfulness practice cultivates a nonreactive form of sensory awareness, which should result in a reduced attentional blink. As we predicted, after three months of an intensive retreat, the meditators perceived both numbers more frequently than the controls did. This improved perception was also reflected in lessened activity of a particular brain wave in response to the first number. Monitoring the P3b brain wave, used to assess how attention is allocated, indicated that meditators were capable of optimizing attention so as to minimize the attentional blink.

Staying aware of an unpleasant sensation can reduce maladaptive emotional responses and help one to move beyond the disagreeable feeling and may be particularly useful in dealing with pain. In our Wisconsin lab, we have studied experienced Practitioners while they performed an advanced form of mindfulness meditation called open presence. In open presence, sometimes called pure awareness, the mind is calm and relaxed, not focused on anything in particular yet vividly clear, free from excitation or dullness. The meditator observes and is open to experience without making any attempt to interpret, change, reject or ignore painful sensation. We found that the intensity of the pain was not reduced in meditators, but it bothered them less than it did members of a control group.

Compared with novices, expert meditators’ brain activity diminished in anxiety-related regions—the insular cortex and the amygdala—in the period preceding the painful stimulus. The meditators’ brain response in pain-related regions became accustomed to the stimulus more quickly than that of novices after repeated exposures to it. Other tests in our lab have shown that meditation training increases one’s ability to better control and buffer basic physiological responses—inflammation or levels of a stress hormone—to a socially stressful task such as giving a public speech or doing mental arithmetic in front of a harsh jury.

Several studies have documented the benefits of mindfulness on symptoms of anxiety and depression and its ability to improve sleep patterns. By deliberately monitoring and observing their thoughts and emotions when they feel sad or worried, depressed patients can use meditation to manage negative thoughts and feelings as they arise spontaneously and so lessen rumination. Clinical psychologists John Teasdale, then at the University of Cambridge, and Zindel Segal of the University of Toronto showed in 2000 that for patients who had previously suffered at least three episodes of depression, six months of mindfulness practice, along with cognitive therapy, reduced the risk of relapse by nearly 40 percent in the year following the onset of a severe depression. More recently, Segal demonstrated that the intervention is superior to a placebo and has a protective effect against relapse comparable to standard maintenance antidepressant therapy.

COMPASSION AND LOVING KINDNESS
The third form of meditation under study cultivates attitudes and feelings of loving kindness and compassion toward other people, whether they are close relatives, strangers or enemies. This practice entails being aware of someone else’s needs and then experiencing a sincere, compassionate desire to help that person or to alleviate the suffering of other people by shielding them from their own destructive behavior.

To generate a compassionate state may sometimes entail the meditator feeling what another person is feeling. But having one’s emotions resonate empathetically with the feelings of another person does not by itself suffice to yield a compassionate mind-set. The meditation must also be driven by an unselfish desire to help someone who is suffering. This form of meditation on love and compassion has proved to be more than just a spiritual exercise. It has shown potential to benefit health care workers, teachers and others who run the risk of emotional burnout linked to the distress experienced from a deeply empathetic reaction to another person’s plight.

The meditator begins by focusing on the unconditional feeling of benevolence and love for others, accompanied by silent repetition of a phrase conveying intent, such as “May all beings find happiness and the causes of happiness and be free from suffering and the causes of suffering.” In 2008 we studied experienced volunteers who had practiced this form of training for thousands of hours and found an increase in activity in several brain regions while they listened to voices conveying distress. The secondary somatosensory and insular cortices, known to participate in empathetic and other emotional responses, were more activated for experts than controls in response to the distressed voice, suggesting an enhanced ability to share the feelings of others without reporting any sign of becoming emotionally overwhelmed. The practice of compassion meditation also produced more activity in areas such as the temporoparietal junction, the medial prefrontal cortex and the superior temporal sulcus, all typically activated when we put ourselves in the place of another.

More recently, Tania Singer and Olga Klimecki, both at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, in collaboration with one of us (Ricard), sought to distinguish differences between the effects of empathy and compassion on meditators. They noted that compassion and altruistic love were associated with positive emotions, and they suggested that emotional exhaustion or burnout was, in fact, a kind of empathy “fatigue.”

According to the Buddhist contemplative tradition from which this practice is derived, compassion, far from leading to distress and discouragement, reinforces an inner balance, strength of mind, and a courageous determination to help those who suffer. If a child is hospitalized, the presence of a loving mother at his side holding his hand and comforting him with tender words will no doubt do that child more good than the anxiety of a mother overwhelmed with empathetic distress who, unable to bear the sight of her sick child, paces back and forth in the hallway. In the latter case, the mother may then end up with the common experience of burnout, which, in one U.S. study, beset about 60 percent of the 600 caregivers surveyed.

To further explore the mechanisms of empathy and compassion, Klimecki and Singer divided about 60 volunteers into two groups. One meditated on love and compassion, and the other experimental regimen trained participants to cultivate feelings of empathy for others. Preliminary results showed that after a week of meditation-based loving kindness and compassion, novice subjects watched video clips showing suffering people with more positive and benevolent feelings. The other subjects, who devoted a week to an experimental regimen that just cultivated empathy, experienced emotions that resonated deeply with others’ sufferings. But these emotions also brought about negative feelings and thoughts, and this group experienced more distress, sometimes to the point of not being able to control their emotions.

Aware of these destabilizing effects, Singer and Klimecki added training for the empathy group in compassion and loving kindness meditation. They then observed that this additional exercise counterbalanced the detrimental effects of training in empathy alone: negative emotions diminished, and positive emotions increased. These results were accompanied by corresponding changes in the areas of several brain networks associated with compassion, positive emotions and maternal love, including the orbitofrontal cortex, the ventral striatum and the anterior cingulated cortex. The researchers, moreover, were able to demonstrate that a week of training in compassion increased prosocial behavior in a virtual game specially developed to measure the capacity to help others.

A DOOR TO CONSCIOUSNESS
Meditation explores the nature of the mind, providing a way to study consciousness and subjective mental states from the first person perspective of the meditator. In a collaboration with expert Buddhist meditators at Wisconsin, we have studied the brain’s electrical activity using electroencephalography (EEG) during compassion meditation in which the meditators described the well-defined sense of self as becoming less fixed and permanent.

We found that these long-term Buddhist practitioners were able, at will, to sustain a particular EEG pattern. Specifically, it is called high-amplitude gamma-band oscillations and phase synchrony at between 25 and 42 hertz. The coordination of brain oscillations may play a potentially crucial role in the brain’s building of temporary networks that can integrate cognitive and Affective functions during learning and conscious perception, a process that can bring about lasting changes in brain circuitry.

High-amplitude oscillations persisted throughout the meditation for several dozens of seconds and gradually increased as Practice progressed. These EEG traces differed from those of control subjects, in particular, in the lateral front oparietal cortex. Changes in electrical activity may reflect an increased awareness in expert meditators of their surroundings and their internal mental processes, although additional research is needed to better understand the functioning of gamma oscillations.

Meditation brings about changes not just in well-defined cognitive and emotional processes but also in the volume of certain brain areas, possibly reflecting alterations in the number of connections among brain cells. A preliminary study by Sara W. Lazar of Harvard University and her colleagues showed that among longtime meditators, as compared with a control group, the volume of the brain’s darker tissue, its gray matter, differed in the insula and prefrontal cortices—specifically, regions called Brodmann areas 9 and 10, which are frequently activated during various forms of meditation. These distinctions were most pronounced in older participants in the study, suggesting that meditation might influence the thinning of brain tissue that comes with aging.

In a follow-up study, Lazar and her colleagues also showed that mindfulness training decreased the volume of the amygdala, a region involved in fear processing, for those participants who showed the most noticeable reductions in stress over the course of training. Eileen Luders of the University of California, Los Angeles, and her colleagues further observed differences in meditators in the fibers called axons that connect different brain regions, suggesting an enhanced number of brain connections. This observation may support the hypothesis that meditation actually induces structural alterations in the brain. An important limitation of this research relates to the lack of long-term longitudinal studies that follow a group over the course of many years and to the absence of comparisons between meditators and people of similar backgrounds and ages who do not meditate.

Some evidence even exists that meditation—and its ability to enhance overall well-being—may diminish inflammation and other biological stresses that occur at the molecular level. A collaborative study between our group and one led by Perla Kaliman of the Institute of Biomedical Research of Barcelona showed that one day of intensive mindfulness practice in experienced meditators turned down the activity of inflammation-related genes and altered the functioning of enzymes involved with turning genes on and off. A studyby Cliff Saron of the University of California, Davis, looked at the effect of meditation on a molecule involved with regulating the longevity of a cell. The molecule in question was an enzyme called telomerase that lengthens DNA segments at the ends of chromosomes. The segments, called telomeres, ensure stability of the genetic material during cell division. They shorten every time a cell divides, and when their length decreases below a critical threshold, the cell stops dividing and gradually enters a state of senescence. Compared with a control group, the meditators who showed the most pronounced reductions in psychological stress also had higher telomerase activity by the end of the retreat. This finding suggests that mindfulness training might slow processes of cellular aging among some practitioners.

A PATH TO WELL-BEING
About 15 years of research have done more than show that meditation produces significant changes in both the function and structure of the brains of experienced practitioners. These studies are now starting to demonstrate that contemplative practices may have a substantive impact on biological processes critical for physical health.

More studies using well-defined, randomized controlled trials are needed to isolate meditation-related effects from other Psychological factors that can influence the outcome of a study. Other variables that may affect study results are the level of motivation of a practitioner and the roles played by both teachers and students in a meditation group. Further work is needed to Understand the possible negative side effects of meditation, the desirable length of a given practice session and the way to tailor it to a person’s specific needs.

Even with the requisite cautions, research on meditation provides new insights into methods of mental training that have the potential to enhance human health and well-being. Equally important, the ability to cultivate compassion and other positive human qualities lays the foundation for an ethical framework unattached to any philosophy or religion, which could have a profoundly beneficial effect on all aspects of human societies.

MJ on Work, Failure and Success

I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. 26 times I’ve been trusted to take the game winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed. –Michael Jordan

ISP More than Triples Speed

Today, I got a letter from my ISP saying that they are giving everyone a free upgrade from 15mbps to 50mbps.

As reported previously, without a VPN, I would get around 11-14mbps and after installing a VPN, I've been consistently getting over 30 mbps.

Well, after this free upgrade, I tested with and without a VPN.

With a VPN, it was coming in the 40mbps range.  With the VPN, I'm consistently getting over 100mbps now.

This is a nice Christmas gift from my ISP.
