Have a friend whose kid has severe peanut allergies (as in, eat peanuts, get that epi pen out because it's gonna get life-threatening fast.)

Not fun at all. I'm glad I don't yet have any allergies like that.

Heard the story of an old lady who shows up at the hospital, severe allergic reaction to peanut butter...says she ate a PB&J every day the last umpteenth years. Weird!
