Can you handle it?
Popular tourist havens are inevitably a bit on the germy side — it’s kind of hard to avoid it when you have thousands of people from different parts of the world coming and going.
You never really know if everyone around you is being responsible about hand washing or covering their nose when they cough or sneeze. Luckily, you can anticipate these uncertainties and prepare accordingly.
That said, there are some particularly disgusting attractions where all bets are off.
If you're squeamish, you might want to turn back now. All others, proceed, but be warned — you might feel a compelling need to wash your hands afterward.
