In all fairness, there should probably be some sort of special line for the elderly to allow them extra time to get through security without feeling pressured. While we're at it, let's have a kids line to allow parents the time to get through security without feeling pressured also. (not to mention to keep kids out of our way, right?)

However, which airport do you know of has the space/extra lines to do this? The best thing you can do is get to your airport as early as possible and take a few deep breaths. Or if you really can't handle it, you can start drinking before you go through security, though I believe most people save it for the lounge, but if you're that impatient....
