Anton, surely no one is scrolling up and down the forums at that speed for a minute at a time. Why would anyone do that? You'd not be able to read a word, and would get cramp in your mouse-wheel finger long before a migraine took hold.

As for suing - it implies people are abdicating responsibility for their own health, and a court of law will have as much sympathy for someone in that position as I do. If something is giving you eyestrain or migraines or seizures, then stop doing it.
