Why does everyone try to travel when they're young? There are things youth helps with but visiting other countries doesn't seem like one of them. Finding a partner and building a family is though and that's very hard when you're always in a different place.
Plenty of people end up traveling more than they want to later in life for business anyway.

I remember a beautiful sunrise hike up to the Meteora monasteries in Greece... then the swarms of busses filled with elderly retirees coming in after.
Sure, you can visit places when you're older - but it's a vastly different experience.

Traveling is simply easier when you're young. For example, have you ever wanted to climb Mt. Everest? Guess what, it's going to be a lot easier in your 20s than 60s.
Put it another way, the set of all places you can visit while young is simply bigger than when you're old. Places that require intense physical exertion will be off limits to you.
