I find that when I'm feeling sick (I guess sick = anything worse than typical cold...so bad cold, flu, anything else that makes me feel tired and crappy), I seem to lose my desire to listen to metal. I just feel too run down, like I don't have the energy to enjoy it. Generally I know I'm getting better when I start feeling the urge to throw on some Hibria (or whatever my latest interest is) again. Does it work the same way for most people? I'd guess yes, but no way to find out without asking, so cast your vote and add your comments.
