From what I have heard, a computer keyboard contains roughly 400 times the harmful bacteria of a toilet seat. Doorhandles are also especially gross.

As a male, this is not so much of a problem. My mother indoctrinated me to the religion of germophobia early in life, instructing me on the placement of tissue upon the surface of the public toilet, which is apparently useful in such situations when my gender offers me no standing benefit.

I once began thinking about the reality of the public restroom door handle. Possibly the most bacteria laden thing on earth. Not only do you touch it, but you touch it after you wash your hands. At this point they are slightly damp. After this, you consider yourself clean enough to pick up food with your hand and place it in your mouth.

They say urine is an antiseptic, but I will not be so bold as to reason this with the prior facts to their logical conclusion. Instead, the following advice should suffice:

Sit proudly.
