Generosity Gene

From the BBC: Generosity 'may be in the genes'

The gene AVPR1a plays a key role in allowing a hormone called arginine vasopressin to act on brain cells.

Vasopressin, in turn, has been implicated in social bonding.

The researchers found greater altruism in players in which a key section of the gene, called its promoter, was longer.

The promoter is the region that determines how active a gene is. In this case a longer promoter makes the gene more active.

I would be curious to know if there is someone that never performed a generous act in their lifetime, not even once.

Even a compliment could be an expression of generosity, waiting an instant so you don't hit someone with your car.

Its something to think about.
