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 :)

@4:30 Sorry to be a stickler, but most viruses are RNA viruses. I loved the video... And I loved your video filmed here in Western Australia with the boys from How rediculous. I live in Perth, too bad you didnt have a meet up event... I love your channel. It consumes many hours of my free time...

Mark Rober my family goes on 30 minute walks and we go to our friends houses, ring the doorbell with our elbow, then run back to the sidewalk and have a conversation like that.

Japan does not have that many deaths compared to New York and that is because Japan use masks instead of social distancing.

Why not talk about how the human body is basically viral itself. And the fact that killing 99.9% of bacteria only creates the environment suitable for superbugs to flourish. Just as antibiotics destroy the natural balance of good and bad inside the gut, hand sanitizer and Lysol do the same.

I'm here from April 4th to say... It's hard to unite people when behind a faceless enemy. We are to busy trying to find someone to blame and be the one who's "right" in a no win scenario, that we hit the curved harder then any other country.

@jenn lemmelin That is partly true, virus are not alive by DEFINITION. That's because they need another organism to live. When we say that a virus lives in a surface, we mean that if someone touches the virus, it's still able to infect him

I enjoyed this video, but I think it's important to point out that it's not that people think it's okay to go to work sick, but that people need the money and there's not enough paid sick leave for them to do so. People will go to work if they're sick now because they're worried that they'll get sicker later and need that time. We should give more sick time to employees, and create a work culture where it's okay to not work if you're sick.

You say that we should be more careful when we are sick with the flu, but what about school? Upperclass kids need to be at school otherwise you will end up being way behind. So school literally force kids to come to school sick. What do you suggest?

@mixio hili What difference does that make concerning the spreading of ANY DISEASE........NO disease has independent locomotion,they ALL rely on transmission from host to host BY THAT HOST'S PHYSICAL ACTIONS. THAT WAS THE WHOLE POINT OF THE VIDEO.........TRANSMISSION

The corona virus has no DNA. It's not "alive" like a bacteria. It does, however, have RNA. A virus can only have one or the other.

Thank u Mark - awesome stuff! Is there a way u could compare wearing gloves to using hand sanitizer? (Cashiers/baggers). Also wearing a mask? I know u cant put this powder in ur mouth but maybe another idea to show results?
