Yeah, I have pretty much given up on licking doorknobs, too. It was a struggle...

I have never taken a flu shot. It's not lack of trust, but the flu shot almost never hit the strain exactly so it's not that much use. I really believe in the 'lifetime' vaccines like smallpox, measles, whooping cough, etc. I suspect they will tie the vax to travel so I'll have to take it. I want to go to Canada and Mexico and suspect it will be mandatory for those two borders.
