I must be crazy lucky. None of that stuff causes a reaction with me. One time when I was living in Minneapolis, I was playing disc golf with some friends (yeah, I know. This sounds like the start of a bad hipster joke) and I threw a disc into a patch of poison ivy. Interestingly enough I didn't know what poison ivy looked like, so I went hands and knees trying to find my disc. The people I was with freaked out a bit. Not a thing happened. I've even tried rubbing different stuff on a part of an arm or leg and nothing happens. Definitely not going to complain about it!
