I have a stomache of steel. Nothing will pass my digestive tract alive or intact. I never had any kind of stomache trouble and I can not puke. I ate every dish in south-east-asia that landet in front of me, even from some dirty streetfood shack in the middle of the burmese jungle. Most of the stuff would have killed the average middle european slob. Not me.
It even goes so far that I cannot use edibles. Which is funny, because all the growmies make fun of me now.
Cash money, that’s where the real danger lurks. Even if you can drink bottled water and eat pre-packaged food, you have to handle the money. And that stuff is really, really nasty in some parts of the world.
