You do know it's an acquired taste, right? Once you build a tolerance to the perceived hotness of it, you actually are able to appreciate the plethora of different tastes in it. However, you're right in so much that you have to basically burn your face off to get to that level. Personally, I can't get enough of it. It makes every meal a challenge.
I'd go for the ability to see the future, probably. The idea of changing the sequence of time kind of unnerves me and I wouldn't want to **** with it. Never know what could happen. But I'd also only use the ability to see the future sparingly, like to win money through gambling. Or to see the future of humanity millenniums into the future. You know, simple stuff like that.
An interesting question, so SQ
