Dr Tang recommends that if you see someone walking towards you, it’s best to take a quick breath in and then you exhale out after you’ve walked past them.

“Holding your breath is good but if you breathe out, it’s even better, because you then blow any virus away,” he says.

So you can just blow-away a virus.... SCIENCE!!!!!!

Sure, if you had a 30 foot wide umbrella, you won't get wet from rain ever, but is it worth carrying the umbrella?
