Re: Coronavirus
The %age risk of anything is meaningless the more times you take that risk.
Eg If something occurs when you throw a double six with a pair of dice, the more times you throw those dice, the greater the chance that one of those times a double six will appear.
A 50% reduction is meaningless, unless the incidence in others is low in the first place. If you meet up with several people, several times, who are all infected, that 50% reduction goes right out of the window.
