Computers have been more in the realm of the younger generations for a long time now, and young people can handle bad posture and other things more easily than the elderly can. I mean we're waiting on them to reach the age where their body can no longer handle it.
My dad had a business installing mainframes when I was young - back when mainframes were still installed in individual businesses, you know. At the time I was a kid, but I know we always had some of the first tech on the block, so I doubt many had tech before me.
I'm reaching the age where I can no longer handle a bad posture - I assume this is going to start getting bigger in the next 5-10 years. I could be wrong, I dunno, but I don't think so.
