I have a 2 year old daughter and I'm about to have a son in February. Walking away from them is unfathomable. I can't imagine the regret I'd feel at my old age, having lost the few short years where I get to watch my children grow up, just so I can walk to some places.
There's far more depth and mystery to be explored in raising a human than there will ever be as a tourist. The deep stupidity it takes to think otherwise is depressing to behold.
