Why is traveling such a big deal for people?

Disclosure: I've traveled and I've lived abroad in two different countries and been dozens of places outside of my 'home'. But I don't get this…

Human variation…

Some people are cool anywhere.

Some freak out when they leave home.

Some have to leave and never come back

And some have to ping pong all over the damn place constantly.

If everyone was the same we’d never have made it anywhere close to this far.
