| I have lived in 3 continents (Africa [Nigeria], Asia [India], and North America [US]) and vacationed a few times in Europe [mainly England and Switzerland]. This, IMO is good advice. Contrary to popular belief, people around the world are good. They are willing to help you out and are less likely to take advantage of the fact that you are new there. There is also a sense of curiosity - about who you are, where you are from and what you think of their lands of origin. It often gets a little tiring answering all those questions. :) On the other hand, governments and officials especially in third world countries tend to be corrupt and agenda-driven. It's amazing how much money changing hands can do, and this I believe is a big deterrent to foreigners in many lands. You need to be a little street smart and know how to work your way out of a potentially sticky situations. I agree with other comments on HN that you need to be careful of germs. I spent a year in the US before heading back to India to visit family, and I had food off of a street-vendor. I was sick for the next 3 days (God help me now that I have been here for a decade :D). Living in a very sanitary environment like the US can (potentially) weaken your immune system [1]. Ensuring that the food is sealed, or at the very minimum hot is a good way to avoid some of the pitfalls. On the other hand, I have eaten at locals homes in Nigeria, and don't remember having any issues (it's been a while since I was there). This article makes me want to drop everything and take off for a few months. Sadly, that won't be happening anytime soon. But if you were to take away one thing from this article - it is that you should travel. Going to most countries in the world does not have to be expensive, and it will give you a good way to find out about other cultures, and potentially give you a new avenue into your own [2] [1] - I am not a doctor, but this has been my experience. I tend to be susceptible to unclean water and food - even the pollution in big cities like Bombay affects me way more than it did when I lived there. [2] I was raised in a western culture - watching NBA and CNN, listening to pop and rock music, and reading Archie and Mad magazine. But after coming to the US, I have come to realize that there is a lot of things the Indian and American cultures have in common - even more, that there is a lot they can learn from each other. |
There are lots of vague hypotheses like this floating about, but IMHO[1] they're pretty flimsy. The fact that you don't have immunity to various foreign bugs doesn't imply (at all) that your immune system is "weak".
There's better evidence that sanitary conditions could increase allergy, which is an overactive immune system, not a weakened one.
Pollution, which you mention later in your comment, has nothing at all to do with immunity.
All that aside: boil it, peel it, cook it, or forget it!
