My question is about the cleanliness of loofahs and other body scrubbers. Since they usually hang out in the shower where there is constant warmth and moisture, wouldn't they grow bacteria? How often should they (scrubbers) be changed or how do you clean them? The reason I ask is that I am experiencing some hives, and the only thing I can think that is causing it might be the scrubber gloves in my shower.

My eyes are light-brown, and when I've been crying or when it's bright outside they look greenish. I want my eyes to be that greenish all the time. I heard that putting honey in your eyes will lighten them. Are there any side effects? Is it bad for my eyes?

Is it true if a guy holds his urine too long it can damage the prostate and make it harder if not impossible to have boners or be aroused?

Lately, I've come to realize that I have a very powerful tendency to fall asleep in class. It seems that I can't stay awake in any lecture style class where I have to listen to the professor and take down notes — where there is minimal engagement on my part. I've pretty much fallen asleep in all of my lecture classes, during one part or another for the whole semester. I think I'm getting regular sleep — six hours at a minimum. I don't like to drink coffee or anything.
