Generally, primates form groups, and have 'cultures' of sorts. Higher primates take care of their sick too, its not just humans. Although they may not be the most 'fit' the unhealthy can still add value to a group (be it human or chimp). The correlation seems to be that the smarter the animal, the more it cares for the weaker members in its group.
I guess it makes sense on a board like this, but everything seems to come down to fat vs fit. If you are fat then you are a 'mindless drone', and if you are fit then you are a top human specimen both physically and intellectualy. However this board is exaclty like the "money is what society dictates that we need to move higher in the eyes of others" scenario you describe, however instead of money, its muscle. Is a muscle focus any better than a money focus?
