The premise that genes control life is known as biology's Central Dogma. But what is coming into clearer light is that in order for genes to be activated something in the environment must act as a trigger. Epigenetics is the study of the molecular mechanisms by which environment controls gene activity, and today it is one of the most prolific areas of scientific inquiry. The answer is not some quick fix prescription drug. Remember, every time a drug enters the body to correct one function, it invariably throws off several other necessary functions. A phenomenon all too familiar to anyone who has experienced side effects from a drug. For example, anti-histamines used to treat allergies also act on the brain to produce drowsiness, a side-effect that is either celebrated or deplored depending on the occasion. There is a time to doze, AND IT IS NOT WHILE READING THIS POST! That we are more than just our DNA is evidenced by the fact that our chromosomes or set of inheritable traits are composed not just of a mixture of nucleic acids (DNA) but also, and perhaps more importantly, of proteins. 

The proteins surrounding the DNA regulate our genes' expression. And they do so in response to the environment of our cells. When we provide a healthy environment, by eating fresh whole foods, exercising regularly, getting adequate sleep, and thinking happy thoughts, the body responds, our health improves, as does the health of our children. The opposite is true. Stress out, fill yourself with toxins, and spend your day on your backside with excessive exposure to the electromagnetic radiation emanating from your cellular phone, and your derrier in addition possibly to tumorous growths, is likely to expand. Your baby's booty too.

Even Charles Darwin, who fathered the Central Dogma by according almost exclusive control of our evolution to our genes, lamented in his later years that he had neglected the direct action of the environment - food, climate, and other factors - that work independently of natural selection. And this makes intuitive sense. As Bruce Lipton notes in his book The Biology of Belief, "genes cannot preprogram a cell or organism's life because survival depends on the ability to dynamically adjust to an ever-changing environment."

While it is true that some diseases like cystic fibrosis and certain neurological disorders can be blamed entirely on one faulty gene, these single-gene diseases affect less than 2 percent of the population. Today's scourges - diabetes, cancer, heart disease - are not the result of a single gene but of the interaction between several genes and environmental factors. And only about 5 percent of cancer and cardiovascular patients can attribute their diseases to heredity. There has been much talk about the BRCA mutations and breast cancer, but it must be stressed that ninety-five percent of breast cancers are NOT due to inherited genes, and of those with the BRCA mutation, only about half actually get cancer.

Humans and rodents have about the same number of genes, and we are certainly more complex than rats. So what accounts for the greater complexity? The extra proteins that govern the expression of our DNA. Humans can survive with far fewer genes than scientists once believed because the same gene products, which are proteins, can be used for a variety of functions, similar to the same letters of the alphabet making many different words. Like Meal and Lame. Personally I prefer the former. Five of them a day, mostly fruits and vegetables. Anything less and I feel lame, meaning I haven't the energy to run.

Which is why the Central Dogma has been revised to include Environment and Regulatory Proteins at the top before DNA and RNA and Protein, and the influence is not one way but a reciprocal interaction at every level.

So if environmental factors such as nutrition, stress and emotions influence genes by governing epigenetic changes, and methylation reactions are involved in epigenetic changes, then eating a diet rich in foods with methyl groups (B12, folic acid, choline and betaine) would seem to drive genetic expression in the direction of favorable traits. Such as weight loss in lab animals. I'm serious! Which is probably why I'm loving egg yolks these days. It's an excellent source of choline. But more than anything, biological behavior can be controlled by invisible forces. Not just EM radiation but thought, which can be as effective as medicine in curing disease, and without the side effects. Pharmaceutical-free energy medicine is a real thing and gaining momentum. "Control of our lives is not in the genetic roll of the dice at conception but in our own hands," writes Lipton. Or in our own minds. And the mind, according to latest research, is located not in the brain but is distributed via signaling molecules over the entire body. You are a walking, talking, thinking, feeling brain. And your thoughts have sweeping ramifications the importance of which is only beginning to be fully understood. 

Take home message: you are what you think, so think happy thoughts. That is, if you choose to think at all. I prefer to make like a tree and BE.

I was watching the TV show Naked and Afraid last night as I sometimes do. The show teams together two strangers, a man and a woman, who attempt to survive on their own for a period of 21 days in some remote and isolated region. Some of the locales featured include the Australian Outback, the Amazonian rainforest and the African Savanna. The man may have a military background, or be an adventurist or deep sea fisherman. Sometimes he's an ordinary dude who lives with mom. The woman is a park ranger or extreme fitness enthusiast or "just a mom" herself. Sometimes the couple quarrel, sometimes one or both "tap out" (quit) in a fit of anger or illness. It is satisfying to see them actually make it through the challenge and reach their extraction point. The victors are usually exhausted, emaciated, begrimed and bare ass naked. 

Even more satisfying, at least for me, is the occasional ass shot, snuck in at strategic intervals to boost viewership, of course. It's co…


I hereby proclaim that June is meditation month. And July and August and some of September too. For me at least. During the hundred days that comprise summer, give or take, I have taken it upon myself to "assume the position" for approximately one hour each day, usually divided into two 30-minute sessions. During this time I sit in front of a candle flame, let my breathing subside, and with it my mental activity, and literally count the seconds.

The reductive tendency that is emblematic of science has penetrated schools of meditation, and there are many, each of which advertises its particular breed as, if not being the best, at least boasting novel or specific benefits not found in other forms of meditation. 

For example, there is mindfulness, which is the monitoring of thoughts. There is concentration or focus, as on an object or the breath. There is transcendental meditation, which uses the inward repetition of a phrase, or mantra, to "allow your active mind to easily …


To be spontaneous or systematic, that's the question. Or SOS, as the Police sing. Within me these two opposing characteristics are ever at war. I suppose we're all born more of the former. What child is not up for a trip to the candy store on a whim? But our educational system drums in the systematic approach to problem solving. You must progress from number 1 to 10 on your test. Each class is 50 minutes long. Etc. And indeed having a schedule and being methodical can lead to greater material success. If you only do what you feel like you may never study math, or organize your closet. But enslaving yourself to a ritual can suck all the fun out of life. To reconcile the two approaches we've evolved the weekend, which is basically a short vacation from the rigid workday, a time to play in an unstructured way. The athlete has his rest days, a time away from play. The family has the trip to the Bahamas. There are semester breaks in school, though having an entire summer off is…
