Why do I eat Habanero, I know it's going to bring pain?

Why do I eat Habanero, I know it's going to bring pain? There are times on the weekend when I will make some eggs with ham and side beans with cheese, and instead of dashing some hotsauce, I will get a full habanero and cut into pieces and eat it raw like that, seeds and all. It gives this weird sensation in my scalp and makes my nose runny and I some times will have like 1 or 2 tear drops come out. WHY, do I do this? It's almost like a HIGH, that scalp sensation is crazy hahahaahahaa.
