    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...

    Handshaking is obviously not ideal during a deadly pandemic, but wouldn't it be beneficial toward all of our immune systems to continue the practice when there is no life threatening danger? The more we isolate ourselves from germs and viruses the less natural immunities we develop, leading to a future where our species is weak.

    The body is filled with bacteria and viruses at all times. Some viruses play the role of breaking down harmful bacteria (they are called phages). Seasonal flu viruses mutate/change each year. Getting vaccinated for last year's flu virus may not help with the strain of virus that is out this year. I am cautious about having any virus 'vaccine' administered on a massive scale. Each year during flu season many thousands of immune compromised individuals die of complications, more so than with this present 'pandemic'. In Canada, in 2009 research, scientists studied 2000 individuals and discovered that those persons who had been vaccinated for the seasonal flu virus were twice as likely to get the H1N1 swine flu. Now what does that say about flu vaccine. It indicates that flu vaccines may even weaken the body's natural immune response to resist viral infection of another strain. The best advice is self-isolation, public gatherings shut-downs, plenty of sunshine/fresh air/clean water, good food habits, and vitamin A, C and D to stop this present viral outbreak in its tracks. This is what China, South Korea and British Columbia, Canada are finding successful. I am very skeptical of Gate's plan to sell the world billions of dollars worth of questionable 'vaccines'....every time some 'new strain of seasonal virus' springs up.

    Hi Mark, thank you for this video, I've shown it to my students to emphasise on how we could pass viruses without us even knowing it. Singapore school are going into Home Based Learning for a month, I think I was able to put my message across with your help. Stay safe. And BTW, my students said you are cool 🤣🥰🥰

    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.

      @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
