I know the kind of conditions that the people of Vietnam and Afghanistan were raised and survived in were many many times harder than the conditions that Texans have lived in their whole lives. You should too if you have paid attention to your education on world history.

Really not that hard to understand that people who grew up in third world countries are better equipped to deal with surviving off of the land and living with no amenities than people that grew up in first world countries.

We can have a pretty damn good clue based on how they live and behave day-to-day.
