If you have the privilege of checking into a Jordanian hospital with a stomach ailment, they’ll either want to take out your appendix or (if you’re female) just tell you that you’re pregnant. "Same same." That being said, it’s pretty easy to stay healthy in Jordan, especially if you resist the urge to drive everywhere and spend time walking up and down Amman’s steep hills. Street food is no problem; I lived on it for five months and my vital organs seem to be functioning properly. Just try to keep your shisha intake to a no more than a few times per week, lest you burn up your lungs (I probably should have taken my own advice on this one).
