If you KNEW that eating a partcular food would make you sick would you still go out of your way to keep eating it?

I avoid whatever I know will make me sick. Food situations people. Perhaps it's just that I don't have time to waste.

Some seem to go out of their way to engage with people who make them sick...at least figuratively. Now why is that? What's the lure when you KNOW in advance what the time spent will result in for you? It's always is the same. It never is different. I don't get it.
