Psoriasis and donating blood

[Caroline]

A bit of statistics. I put it here, as I think this is the most relevant place.


At every cm2 of your skin there are living 2000 bacteria. Your and my mouth contain more than 600 different types of bacteria. Dent plaque (on your teeth) consists for more than 50% of bacteria. 1 cubic cm of dental plaque can contain as much as 10 000 000 000 bacteria.
In your intestines are living about 100 trillion of bacteria. You have 10 times as much bacteria in your intestines as there are cells in your body. So basically a human consists for 90% out of bacteria and for 10% out of well .... human.

You cell phone (or Freds wall-phone) contains on average 18 times as much bacteria as there are on the doorknob of a public toilet. And according to the University of London, 14% of the paper money contains as much bacteria as a dirty toilet pot.
Still about 60% of the people do admit: "I never wash my hands before dinner."

I mean..... one could imagine that there is a tiny relationship between Psoriasis and bacteria as they are so overwhelmingly around us people.
