1) We are (as a species) pretty blamed stupid in so many areas that it is hard to believe that we are (at least for now) the "King of the Hill". The question of fat intake is a great example. If we want to know what sort of fats are best for us all we need to do is to take a lawn chair out into the great plains of Africa and observe. What are they eating over in the primate area? Nature seldom wastes time or energy.

2) The question of reduced circulatory flow to the brain is one that I plan to investigate at some future date by testing an extract of the common garden plant *vinca minor* or lesser periwinkle. Seems an excellent vasodilator within the brain and surprisingly safe. It is called vinpocetine and costs less than ten bucks for a month's supply.
