This is a fascinating topic, OP. We hardly even consider the effects of physical improvement on our mental capacities.
The following links have information that supports the idea that physical exercise helps develop and maintain cognitive abilities in all ages:

Naturally there are more, but these should be enough.
While initially I just thought of this as an interesting topic when it came to individual self-improvement and study, two related subjects came to mind:
>Fat acceptance
>Helicopter parenting.
Fat acceptance, which is a way of discouraging individuals to take part in lifestyle changes that decrease their fat body mass, includes the ridicule of individuals who take part in physical activities because they are traditionally associated with a shallow pursuit of an idealized appearance. One could argue that this discouragement also -if not primarily- targets the populations cognitive abilities. Now you've got me wondering about the effects of diets on the mental and neural development on individuals...

Helicopter parenting seems to be a growing trend that, among other things, is characterized by an increase in the control that parents have over their children, usually for "their own good". Besides focusing on studies and other forms of monitoring, strict regulation of a child's play activities is an integral part of it, which could include the selection of less risky (read "physical") activities for the children. This can be associated with the growing paranoia over child abuse and urban violence.

OP, I'm afraid I don't understand what you mean with your subject. Can you explain?
Also, the term "memetic warfare" has popped up with increasing frequency here in 8chan, especially since the creation of /bmw/. Since you use the term I assume you are familiar with it. Would you be so kind as to define that term, perhaps in a new thread? I am sure not only I but also other anons would be grateful.
