As early as 1995, neuroscientist Carl Cotman, who studies aging and dementia at the University of California at Irvine, published a paper in Nature showing that physical exercise produces a protein that helps keep neurons from dying and spurs the formation of new neural connections in the brain. More recently, Cotman demonstrated in studies of elderly dogs and mice that enriching their social environment is associated with improvement in brain function...

Having all those alleles hampers the masculinization of some parts of the brain that affect personality, making you gay, the theory goes. Brothers of gay men who have only some of the alleles would turn out straight but less aggressive than typical guys. And because those brothers exhibit less psychopathology, they would attract more women and therefore have more kids...
