In the summer we go from an air conditioned house to an air conditioned car to an air conditioned office building and cringe when we have to get out in the stifling heat for a few seconds.
If this is hust a 100 year starship and you're born half way through the voyage, there's a good chance you'll be alive at the end of it. Now THAT would be something!
