Aren’t your taste buds dead?
You might think they are, based on how some of us can handle some supremely spicy stuff. It isn’t taste buds dying, being burned off, or any of that. That stuff doesn’t happen until you’re old. The desensitization usually only lasts for an hour (or 24, in extreme cases) before wearing off. It’s just the fact that we’re tough… or possibly insane.
Why do you have to have spice in your meal?
We don’t have to have it, but it certainly makes everything more interesting -- it’s an exhilarating experience, not unlike a roller coaster, but without the 40min line. The slight nausea still sometimes remains.
Why are some foods spicy?
It’s due to the presence of capsaicin, a chemical that kinda makes your body think that it’s… burning. But that’s not a bad thing! It just releases endorphins and makes your tongue a little numb, in addition to confirming that you can still feel something -- ANYTHING -- in this topsy-turvy world.
