Exercise Routines and Mental Function

Having been dead many times myself, death is not the problem as it's simply nothingness.  The problem was never death itself but decrepitude, dependency and degeneration of the senses.  That's something to fear and avoid.  Whatever measures that can be taken to avoid degeneration ought to be taken.  That's why one has to exercise daily.  The choice of exercise is all important as some are harmful and some are helpful.  The best exercises stimulate psychic abilities (if one has them).  The better exercises stimulate brain function into neuro-genesis, into making new neurons and the dendrite axial connections between neurons.  There is a lot of research available on the internet comparing the mental benefits of various types of exercise anyone can google and seek out for themself.  If the exercise is not enjoyable for the participant, it won't be continued no matter how beneficial it might be.  Some exercises are so esoteric and restricted, they can't be practiced unless one has access to an instructor in the community in which one lives.  Some exercises are just plain bad, so they ought not to be practiced at all; for instance, any exercise that goes against one's nature.  Some are simply plainly stupid and would actually damage mental function...professional football players and boxers suffer very high rates of Alzheimer and Parkinson disease.  Research, choose, decide; then daily practice what works best for you, as what works well for another won't work the same way for you.  Any exercise routine ought to show immediate benefits that are discernible and measurable in a short period of time.  If real mental and physical benefits are not shown readily available, choose another exercise.  It shouldn't take more than a month after beginning an exercise, any exercise, for benefit to become apparent.
