It is not that the "young" are more aggressive risk takers than olders ones & more "open to ideas".

Most of those older open-minded aggressive risk takers* are now cashiers at the local museum, food demonstrators at Costco, or in some cemetery after some fatal collision.

@nntaleb I'd assume some small percentage of them are wealthy enough not to work and just do Ted Talks about how all you need to do is follow your dreams, never give up, and not understand survivorship bias.
@nntaleb perfect. If you don’t have the temperament, you don’t have the temperament. But presumably the converse is also true…if you do have the temperament for risk taking then you do have the temperament. Like, are you better today than when you were 25?
