I picked "both" because it depends. Some places "mild" is "fucking hot" and some places "fucking hot" is really really mild. I like my spicy food to be flavorful and hot, but not simply hot for the sake of being hot.

Basically, if it damages my taste buds, or puts me in PAIN, I don't want it. I'd say probably anything hotter than Jalapeno is overboard, to me.
