Thought this would be obvious: I was not talking about stuff that makes everybody ill. The body does not adapt well to many other things, but still you can get used to many things that make people ill on first contact.
Why do so many travellers get sick first time they enter a country with different hygienic standard, where the local population has no problem?
btw: I lived 2 years in central Africa, just returned from a 'local meal' in Luanda/Angola.
