I remember reading some months back on reddit I think that exercise has been shown to promote neuron growth in rats. I searched google just now and found this: http://www.paulspoerry.com/index.php/2007/09/14/excersize-makes-your-brain-grow/ http://www.paulspoerry.com/index.php/2007/09/14/excersize-ma... Also, from my experience and from what I've heard/read from others, periodic fasting helps renew the body and slows aging. So here are my suggestions as a non-expert: 1) Exercise as much as possible: at least an hour per day, the longer and more strenuous the better. Exercise in the sun and the open air is preferable. 2) Eat a simple vegetarian diet with lots of colorful fruits and vegetables. 3) Restrict calories, eat slightly less than needed. 4) Fast once a week. 5) Use the mind: converse, read, write. 6) Find something useful to do, a reason to live. Victor Frankl's experience in the concentration camp comes to mind: a person with a strong purpose can endure much. 7) Play music, sing, or at least listen to good music. 8) Avoid contact with cats, because of Toxoplasma gondii, a parasite that gets into the brain of its hosts and affects it. To me, these all seem like common sense measures for good physical and mental health, maybe to you too, but I've been to nursing homes and hospitals where the patients are treated in the opposite way: kept sedentary and indoors, overfed greasy processed foods, relieved of responsibilities that give purpose, and fed an intellectual diet of TV. This regime seems designed to make a healthy person sick, not vice versa.
