Is age a meaningless societal construct?

World culture is focused a little too much on age. It's the defining factor in everyone's life aside from money. Some might even value it more than money since you can get money, but you can't decrease the length of time you've been alive. I don't believe we should value age as much as we do. Of course it needs to exist to keep kids from having sex and doing drugs and so that the elderly can get discounts on crap, but aside from that it's worthless, as John Glenn proves in this video.
