@Thunderloom - I was trying to have a civilized argument not troll you or cause you any offense which is what my last post was about. There is a ignore button though that will hide all my posts if you do so wish for that.
@Kymmie - There is a disease called Beaver Fever cause by a parasite called Giardia. Its cause by a number of things, but has some odd connection with being carried by beavers and their relatives as one route of infection. In the northern Mid USA its a big reason why we boil lake water prior to drinking if we are camping in the middle of nowhere. About grass, Insects don't bother me at all, I love laying on the grass. Again it has to do with parasites. My Zoology class had this amazing way of creeping me out about everything to the point where I lost all caring. If I did something before lecture, without fail we would talk indepth about some pathogen that was related, often parasitic. I lay on grass, Prof talks about how hookworm larva live in grass and soil and can penetrate human skin, I do this
. Leave lecture, big grass lawn outside that building = more of this
. Eventually I came to the conclusion everything exists to carry some kinda pathogen that wants to infect me. So I stopped caring about most of it.
