Electrolytes? Yes. Sugars? No. You are better off drinking pickle juice than any "electrolyte" drink. Gatorade, PowerAde, etc. are all full of free sugars. On both of my century rides (100 mile rides) I drank electrolytes in water and ate salty foods (ham and cheese). I did not need sugars to complete either of them.

Joined in the last couple of weeks. Been talking about and reading about the singularity for years, just never thought to check Reddit for a sub. (I know, my bad). As for optimism... naturally a cynic and convinced that any given revolutionary tech takes far, far longer to implement and become commonplace than any scientist/writer/prognosticator can possibly account for on a regular basis.
