Exercise, for epigenetic’s sake.
I’m heading outside now to do some sprints. Though I don’t particularly enjoy exercising two thoughts propel me: One, that it will only take 10 minutes. Two, that this small investment will send signals to my genome requesting that it express genes disposed toward better health, slower aging, and improved body composition.
I send similar messages by doing fifteen minutes of strength training once or twice a week according to Mark Sisson’s Primal Fitness routine. Most of the exercises require no special equipment and can be done anywhere.
Together, these minimal efforts are estimated to beneficially toggle somewhere between 30 and 100 genes. And it seems to me that it’s working.
