Also, I've recently noticed that unless something is warm (temperature wise), it won't be spicy to me.
I was eating at my parent's house about a month ago and my dad gave me these really hot peppers to put on my tacos.
I loaded it up and felt nothing while he was literally sweating and he's like a master of spice.
Then I heated one up and it melted my face off. I started paying attention to this at subsequent meals to test my theory.
I don't know how but my mouth is now immune to peppers unless they are heated up. And then...I'm in trouble.
