    Please share this with anyone who doubts the science behind social distancing. The road ahead will be a bit bumpy, but we totally got this fellow Earthlings :)

      There's a science sure, and it's all well in theory. But in practise it's totally impossible to avoid catching it. Just like trying to avoid the seasonal flus. You think you can go 2 years without catching it? You're delusional! Even doctors and nurses get it and they know how to wear double masks+glasses+plexiglass in front of them. Anyway don't worry. You're playing dice every time you breathe. it's got only 0.2% death rate. So the odds are in your favor. Unless you're old of course when it rises to 10% range.

    I have a question. Can't viruses and germs "travel" on surfaces? Is there any way that, in a limited amount of time, a virus moves from a spot to another? Do they require someone or something to make contact and then move, that is, can they only stick to surfaces and are incapable of moving on land, or for all purposes on a human hand from the front to the back?

    But doesn't this experiment also demonstrate that this new adapted behavior is absolutely opposite of normal behavior?
