Good point, but what I meant by "old age starting at 40" was more about an increased risk of cerebrovascular accidents, heart attacks, arthritis, gout, loosing your teeth... All those aches that nowadays start at 70.

Also I meant for it to be a funny silly comment, I don't really believe anyone is more willing to risk their life just because their average life expectancy is lower. My bad for not saying "/s" at the end of my comment I guess...
