There have been reports of YouTubers I watch getting sick after eating food in third world countries. However, these countries are also home to a large number of people who do not get sick from eating the same food. I think this suggests that the locals may have developed stronger immune systems. What do you think?
I live in a third world country. What you don’t see in those YouTube videos is how common it is for the locals to contracts sanitary-related diseases such as typhoid fever, hepatitis A, ascaris worms, diarrhea, etc. A large proportion of people I know (including myself) have contacted typhoid fever at some point in their live. Those street food resistance is earned by getting sick a lot when they’re young.
