Yeah, I remember discarding good clothes ( I know, it's bad!), but I felt that, even though I washed them, they were still "contaminated".
I agree totally, we do have good memory, for negative things like sickness.
I get really bad sometimes about contamination. Once I got sick when a certain song was on TV, and I've always hated that song since I heard it then.
Sometimes I form "chains of contamination". Sometimes when I get home from school, I feel like I'm covered in germs, because I was around people. Then, when I touch the remote, that becomes germy, and then if I touch something else after touching the remote, THAT becomes germy. It's so annoying. I always wash my hands a million times after school. Can you imagine all the wasted brain-power I've spent on stupid stuff like that?
