I have this vague memory from when I was very young of being in the back of the family car as it turned onto our street, and seeing all these fire engines and police cars around. Later I either heard or overheard a conversation between my parents where they said that an old man had accidentally lit himself on fire and died, because he was always cooking greasy food and then wiping his hands on his clothes, and as he never changed or cleaned his clothes eventually the grease on them caught fire and killed him.
I have no idea if that’s a true story or not and I rather hope it isn’t, but I think of it in the back of my mind every time I cook greasy food, I swear.
