You've met one now.
My son has it, bad. Seems to be on the increase due to the massive use of peanut oil in manufactured foods, starting in the 1970s.
It can be very deadly. He was almost medivac'd out of Baghdad when he was served some meat cooked in peanut oil (but Army food is the subject of an entire thread on its own...!)
That makes two! Suggest you read my second comment in this thread.
