I guess people generally try to maximize reward per lifetime. Some people try to increase their lifetime, albeit with smaller reward per unit time (eating their spinach). A few rare people try to maximize reward per unit time, even at the cost of a longer life. Felix lived to 56, skydiving all the way. Although he died younger than the average Austrian, he probably experienced greater sum reward. I suppose the gamble is that with his lifestyle, he could have died in his teens - in which case the sum of his reward would be lower than an "eat your spinach" 80 year old. I wonder if you could cross compare: perhaps the sum reward of Felix's 56 fun years is about the same as a Greenland shark's 400 boring years.
