This came up the other night at dinner. Having worked with and seen tons of bacteria in my life (as a former genetics grad student). I am a semi-germaphobe.
Germs are everywhere, even when we think we are being clean. I hate to touch door handles most of the time. However, there is one thing that freaks me out more than anything, and it is using drink dispensers and letting waitresses refill my glass as demonstrated in the second illustration.
Most people are not aware of what is going on.
Can you see it?
