listening to sean moncrieff.......topic allergies

Yesterday there was an American woman who had written a book on her life ,"Dont Kill the Birthday Girl" living with numerous allergies. She was allergic to as a baby,breast milk cows milk ,goat milk soya milk ,plus mustard,cheese, egg, peanuts, mangoes, meat , wool ,leather eggs could actually kill her, she had a huge list, so much so that she was rather cruelly told by a school nutritionist that her body was not meant to survive, anyway she did and it just seems that her life is so restricted , she can only eat sushii in restaurants, and booze is ok.
So what allergies would you hate to have ,or what allergies would make your life hell?....me I would hate to be allergic to Christmas dinners and condoms
