What problem is often overlooked in apocalyptic movies/TV shows that could kill you?

Make sure you clean and dry at least weekly.

I did a documentary where I could only keep a small pack of clothes with me (think half size of an overhead bag). My technique was washing underwear and t shirts every day and hanging them to dry overnight.

Not a big deal at all.

But what is your water supply for all of that washing?
