People routinely get sick when traveling to the point it's basically a trope. Keeping your hands clean is an excellent problem way to reduce your likelihood of getting sick in general.

You, personally, may not get sick traveling, but your experience is not a solution for a systemic problem, nor is your proposal of doing nothing.

It's possible that people who routinely get sick when traveling are the ones that live their lives in self-made sterile cocoons... a tiny sliver of the air-travelling public.

> People routinely get sick when traveling to the point it's basically a trope.

The only version of the trope I've heard of before is eating in foreign 3rd world destinations (eg: Delhi belly). I live in a major tourist destination and if tourists were routinely getting sick out here I'd know about it.

I mean of course one should be washing their hands after using the bathrooom, but all that other stuff you mentioned.. that's anal to the point of obsessive.

Isn't a large value of washing after using the restroom that it means you'll wash your hands multiple times a day when you wouldn't otherwise?

> but all that other stuff you mentioned.. that's anal to the point of obsessive.

Arguments similar to this were used against washing your hands at all when we first developed a theory of germs and contamination.

Really though, this discussion won't progress until one of us has supporting data.

Fair enough.

I don't have data to support my conclusions, but I subscribe to the Hygiene Hypothesis... humans have lived in filth for millennia, and our bodies haven't evolved to live in sterile conditions.
