Seriously, do not attempt a career in science, medicine or anything associated...
Stay safe!
LOL
Nice virtue signaling. Yeah, I get it: "I'm with science, and you're not! Hurrah, hurrah, hurrah!" Yay for you.
It's funny that you and eider profess to know that hand sanitizer kills "nCOV 2019" when you apply it to your hands, despite your admission that you do not even have a scientific way to know that "nCOV 2019" is on your hands (either before, or after, using hand sanitizer), in the first place. Guess what: If there is no "nCOV 2019" on your hands, then, if hand sanitizer used on your hands kills anything on your hands, one thing that it does not kill is "nCOV 2019". Pretty simple: no "nCOV 2019", no "nCOV 2019" being killed.
All I'm asking is, is there a scientific way to know that "nCOV 2019" is on your hands? If there is no scientific way to know that "nCOV 2019" is on your hands--whether before, or after, hand sanitizer has been applied to them--then, obviously, there is no scientific way to know that "nCOV 2019" is being killed when using hand sanitizer on your hands.
Contrary to what masses of media-enthralled imbeciles may think, nobody is a hero, nor even particularly virtuous, for carrying around hand sanitizer and rubbing it on his/her hands all day long.
Here's a question for you and eider to stonewall against:
I "nCOV 2019" on your hands right now? Yes or No.
