That's a little thing that they tell you in high school chemistry classes (remember "reduction–oxidation reactions", or "redox"?), which you then promptly forget. I only remembered because of an unhealthy interest in home-made rocket propellants :).

Clearly no :P Also I realized that, unless I have a specific problem I need to solve, I don't remember or like reading about things. I have been taught things in school/uni that I thought were terribly boring and was bad at, until I needed to solve a problem with that information and then I had to re-learn everything. Kind of a waste of time, but I can't change my brain!
