Replying to Is it worth it

Just watched the trailer for lack of a better and the question was asked about life when they're 60. Sean's answer was he doesn't expect much movement by that age. This got me thinking why? I get that is overstated they won't all be confined to wheel chairs by then but is it worth it. The satisfaction or money or whatever they are looking to get from shooting these massive urban hits. Is it worth sacrificing comfort later on in life. Say they settle down and start a family. How would it feel not being able to play with there kids because they can't stand the pain in their knees and back after half an hour of physical activity. Is it worth the constant arthritis pain and discomfort. Not being able to do simple things like not being able to bring in groceries because they can't handle the extra weight or do simple yard work because it hurts to bend and touch the ground. Should they be pushing the limits now but have to sacrifice later in life?
