Genius...
It's good we have people that do research and keep researching to prevent us from getting more sick.
We've beat so many illnesses and diseases we'd be now where without there knowledge.
It's shocking that even in this day and age people still don't wash their hands properly.
Some don't even use soap. They think wetting their finger tips for 10secs is enough.
Some snort their snot in the street instead of using a tissue or handkerchief.
People sneeze without covering their mouths.
I'm glad there are people out there that try when basic manners and courtesy for others goes down the pan!
