Can mild dehydration cause brain damage in the elderly?

Can being online too long cause brain damage?

• For studies that I'm curious about (and because I live online), brain damage is one of the topics that I've been studying. In particular, I wanted to see if being online too long can have any affect on the brain, let alone cause brain damage. I have been asking several people that question (some of them are in the medical field). Unfortunately, I'm getting mixed reviews and I would like to know from other sources if this is, indeed, possible.

• Answer:

  Maybe that's why we see people walking around with fixed stares and bloodshot eyes. No, you cannot get brain cancer, damage, or the like from to much on-line. What people do get is fat, dumpy and eating to much because they sit on the behinds at the computer all day. Not good. I spend and average of an hour and that's it.
