I think I enjoy regressing. There's a part of living like that that's really fun. It's like there's no consequences: If you want to drink, you drink; if you're hungover the next day and you're late to work, who cares? There's something very appealing about having no accountability in life, but it's just not a way that I had the energy to live forever.
As a traveler, I've often found that the more a culture differs from my own, the more I am struck by its essential humanity.
