Smelling Burnt Toast
Me and my friends always smell burnt toast at school and other places such as at home or outside. It says that this is an early stage of a heart attack or stroke but we are only 16 and can all smell it. Also a science teacher at my school In New Zealand once said that it was the smell of pollution but I don't know if that's true or not. We are all so curious as to what this smell is - please help!
