I think its very natural to dislike travel as you grow older, that has certainly happen to me.

When I was in my 20-30s I had to travel lots for work....I think at one point I had accrued 725,000 airline miles. I flew weekly.

Now I basically dislike travel....I mean I still like visiting my friends, but I wish I could just teleport there and teleport back that night.

The whole routine of trains, planes, and automobiles wears thin. Especially things like sleeping in different beds, dealing with different timezones, languages, routines, etc.

In my youth none of that really bothered me too much, I even relished it....but now it definitely causes a low-level anxiety of dealing with it.
