The hottest dish I ever ate was in South Africa: chicken peri peri. I had too little means to quench the burning sensation on my lips and mouth (beer, rice, sugar), and the aftermath sure wasn't pleasant... But I did manage to earn the grudging respect of the waiter by eating the plate clean.
However, nowadays I tend to go easier on my bowels. I came across an article which indicated that there is a correlation between colon cancer and the regular intake of spicy food: the continuous inflammation isn't healthy for the sensitive tissue lining. In addition, I also want to taste something else besides 'hot' when eating eastern dishes.
