Food and flavor is Geographically very diverse, and a lot of can be an acquired taste. Historically there are very interesting studies on how food has migrated across Geographies! Even the staples like potato has an interesting story!
I can't do hot stuff at all and I don't understand how anyone can. Any kind of chili is all fire and no flavor to me. I could as well just burn my mouth with a lighter to the same effects. Actually chili is worse, because it's still hot when it leaves the body. Even pizza with pickled jalapenos is too much for me.
