Sick

Kim sent this to me:

i did blood work at walter reed for my first rotation of co-op... sometimes we would centrifuge the samples down, which separates the red blood cells from the plasma.  you can absolutely tell if someone has had so much as one cigarette a day, by the turbidity of their blood plasma.  a person who doesn’t smoke has completely translucent blood plasma, but it’s cloudy for smokers.

Sick.  Sick!  Ugh.
