..... Food. Better to enjoy something you like, than slog through the current times.The ability to make any food taste like chocolate. It is very useful.
Would you rather have an infinite amount of your favorite food, the food that you have an infinite amount of will change along with your tastes, or never have to worry about dying of anything other than natural causes.
Would you rather.... watch a volcano erupt (up close, without risk of harm), or.... watch a meteor shower (in which one falls near you)?
