As a business, well thats a different regulatory nightmare.

As for drinking and re-using, yes. Frankly if the stuff they all tell us would kill us, the human race would be extinct by now. Dealing with the traffic on the way to work this morning, that didn't happen. As a kid I camped and ate food off wood of unknown origins and if it fell, we picked it up, dusted it off and ate it anyway. Drank water from springs without filtering it. Swam in waters without lifeguards. Never wore a helmet or knee pads when riding my bike. Climbed trees. Played with matches. Had a pocket knife with me always (Boy Scout), even in school. Went hiking through Florida swamps and woods with little more than a compass and pocket knife to stay alive. Was never bothered by the sharks (only barracuda) when diving. Sailed in waves bigger than my boat. If I skinned my knee, my dad told me to rub dirt on it and go play. I have gone on plenty of dates through high school and beyond and never wore a "rain coat" if you get my drift. I have never used hand sanitizer. I have never had a flu shot. I rarely need an antibiotic for anything and its been at least a decade since I had a flu. The last time I took an antibiotic I think was the late 1990's when I had a bad case of strep throat I couldn't shake myself. By all rights, if the things they say will kill us actually do, I should have been dead long ago. More than half a century of doing all the "wrong" things, I am still just fine.

I have two granddaughters living with us and I let them play in the rain and run barefoot through puttles. I don't care if they put their jackets on, they will know when they are cold. They come inside when they get hungry. They don't own helmets or knee pads (except for volleyball and soccer). I let them climb trees. They run in parks. I let them fall from untied shoelaces and now they tie them because they understand why now. They swim in rivers, lakes, ponds and the Gulf of Mexico, sometimes by themselves. And I take them shooting, but not by themselves. Their older two sisters are just as healthy after doing all those things for a decade and a half too. I am sure they all will do girl versions of all the stuff I did. And I think they will survive it as well.

As for 3D printed items, to be honest, the sponge most people wash their non-3D printed dishware with is far more hazardous. Reasonable caution and alacrity is fine. Treating something like you should be handling it in a Hazmat suit when its uncalled for is not. Would I let the kids lick the bed of a garbage truck? No. Would I make them wash their hands after petting the dog? No. Do I wash the cutting board after slicing up chicken? No. Just kidding there As I said, reasonable caution. Yea it gets washed.

Frankly, hand sanitizer and all this germaphobia is gong to kill us long before any nuke does. Ever watch War of the Worlds (the 1953 version) or listen to it as Orsen told it? WE will be the martians without immune systems before too long if we keep this up. We have an immune system for a reason. Like muscles, if you don't exercise it, the damn thing is going to atrophy into uselessness.
