>Or you'll be in an accident and have to spend a week living with your arm in a sling, unable to use a mouse and keyboard simultaneously. Yep, that happened to me when I was in college; I spent several weeks with my arm in a sling. I was able to use a computer with no trouble. You've obviously never had your arm in a sling; try sitting at a desk in front of a keyboard, and notice the position your arms are in. That's almost the exact same position your arm is in when it's in a sling. The problem (as I found out) with having your arm in a sling is that you can't easily carry things requiring two arms. All in all, I really didn't have many problems with having an arm in a sling. It of course did help that I already used a backpack to carry things. Now walking around with a crutch, on the other hand, was a real impediment to my normal mobility and activities... >At some point, you're going to get old. You'll need glasses and all of a sudden that ultra-thin grey font on a stylish grey background will be a pain to read. This is totally wrong reasoning. That ultra-thin grey font on a "stylish" grey background is a pain to read no matter what your age. It's an effect of stupid hipsters taking over web design in the last 5 years. Graphic design on web pages has totally gone down the toilet in the last few years, and it's hurting everyone who has a brain and any sense of decency. Another factor as far as vision goes: the entire population is now becoming near-sighted: http://www.nature.com/news/the-myopia-boom-1.17120 http://www.nature.com/news/the-myopia-boom-1.17120 >Or you'll get drunk, or try to operate your TV while half asleep. Your cognitive impairment will be an impediment to interacting with the world. Then don't get drunk. And operating your TV is not "interacting with the world", it's mindlessly watching drivel and advertising. Honestly, you sound like you could have made a reasonable argument, but your examples are all completely lousy and just reinforce the other guy's position.

  What happened to your arm? I chipped some bone off the end of my elbow; I couldn't lift anything of any substantial weight. But I had no trouble using my hand to type on a keyboard. I was effectively one-handed for anything that required reaching and grasping, but typing is not like that. And being one-handed isn't that bad with a computer anyway. You can type one-handed (I do it on occasion for short bursts), and you can adopt one of the one-handed Dvorak keyboard layouts. It's obviously not as fast as regular two-handed typing, but it's not bad.

    I dislocated my elbow and it was essentially held at a fixed 90 degree angle.

      Hmm. I'm sitting and typing this right now, and looking at my elbow and it appears to be a 90-degree angle. Also, there's different things you can do to your arm that require a sling. I didn't require a cast for my injury, but even if I did, the sling's purpose is mainly to keep your arm in a neutral position, keep you from bearing weight with it, and keep your upper arm from having to deal with the weight of the cast. It doesn't completely immobilize you; you can usually still rotate your arm enough to use a keyboard. Obviously, though, this depends on your exact injury and what's been done to your arm.
