Might as well live inside a bubble if you’re afraid of a few germs.
While I essentially agree with you....peoples’ hands, and what those hands do, and where those hands go....are things to ponder.
One thing you learn on a cruise ship, and I worked on one for 10 months....and it is not an especially pleasant thought.... is that when you use the handrails...gross though the thought may be....you become intimate with the hygenic habits of perhaps 4000 other people.
I’ll leave it at that. When those norovirus outbreaks happen aboard cruise ships....it’s not because there is rotting food in the kitchens or serving areas. It’s because people with substantially inadequate hygiene habits run their hands over the handrails. And when those outbreaks happen, the crew washes all the handrails with bleach, first thing. Should you go on a cruise ship, the secret to not becoming sick is to wash your hands relentlessly. 10 times a day? Yep. Better than being confined to your cabin or lying in bed with the symptoms of food poisoning for a day or three.
