I guess it is just that dumb manly militancy I have built in me. 
When I was a kid, A forest fire almost came and destroyed our house, And we had to evacuate the area and pick in a few hours what stuff to take and what stuff to leave. I think this has both A: primed me for taking my emotions out of traumatic or high stress situations, And B: made me realise how much I need in the immediate moment when you go from being comfortable to just living day to day. 

A lot of my early solo travel was just a backpack, And I often found myself stuck in a foreign country without money until the next monthly payment, Which in my opinion is the best way to travel. You should not make yourself a burden to locals, But you should also not expect to always see the truth of a place when you pay to be there. What you pay for is to avoid the real work that goes into living in a place and it takes about 6 months being somewhere before anyone can understand the hard work that makes somewhere special. 

Yeah, I blame it on my dumb masculine traits. I can pretty much pass out in an airport or a strange place as long as I know I won’t get killed.
