Query: Optimization of brain and life performance: Striving for playing at the
  top for the long run   In this essay written with my students and collaborators in mind, I share
simple recipes that are easy and often fun to put in practice and that make a
big difference in one's life. The seven guiding principles are: (1) sleep, (2)
love and sex, (3) deep breathing and daily exercises, (4) water and chewing,
(5) fruits, unrefined products, food combination, vitamin D and no meat, (6)
power foods, (7) play, intrinsic motivation, positive psychology and will.
These simple laws are based on an integration of evolutionary thinking,
personal experimentation, and evidence from experiments reported in the
scientific literature. I develop their rationality, expected consequences and
describe briefly how to put them in practice. I hope that professionals and the
broader public may also find some use for it, as I have seen already the
positive impacts on some of my students.
