Probably not a good idea to watch a documentary on germs, viruses, and diseases before traveling.
And... back to packing.
Heck! It’s not a good idea to watch all that and just go out into public!! Other people are gross!
Since those antibacterials will make you sicker than NOT using them….
Germs, in limited quantities are actually your friends….
I rarely use the hand sanitizers. I mostly just wash my hands with soap and water, which I do as often as others use hand sanitizer.
