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…

My ADHD prevents me from sitting still for more than a few minutes, even short road trips are torturous. To add to that, my driving limit due to my disability is about 2 hours and I physically can’t drive at night. I also can’t sleep during the day time.

How TF people survive 12+ hour flights is a mystery to me
