"I fail to see why in an era where people are starting to expect to live until their 80s they should stop working at 65." Cause there's more to life than work?

"I fail to see why in an era where people are starting to expect to live until their 80s they should stop working at 65." Cause there's more to life than work? For most people, vacations are discouraged, and there's lots of stuff that people are told to "wait until retirement" to do. If they're never going to retire, when are they going to do stuff that isn't job?
