SpaceX flight winner gives ticket to friend because he exceeded weight limit

Things that are more dangerous than losing weight at three pounds per week for 26 weeks: 1) not losing weight, 2) going to space and back in a rocket ship.

If his risk aversion is such that he wishes to avoid losing weight at perhaps slightly faster than optimal, then he is being quite consistent to give away the rocket ship ticket. He's exercising ordinary prudence with a little face saving explanation. I do envy his friend.
