it's not just what you eat, it's because of the heat as wll as the possibility of getting some dodgy water as well

a few years ago there was a bit of an epidemic of dengue fever which my cousin caught and it was life and death for a few days so the risks are there even for the locals

and the food makes you poo a lot more as well because it's mainly vegitation, you'll go to a resteraunt and there won't be a veggie menua, there'll be a non-veg menu
