I strongly disagree. I firmly believe that the "proper form" you and I were taught is why carpal tunnel is so common(I don't think it one size fits all) People should do what's comfortable for them. In fact, I'm pushing mid-30 and when I use proper form I get uncomfortable pain, and if I get a chair that doesn't line up the armrest with my desk perfectly I also get uncomfortable pain. It's possible that growing up with computers like I did I found what just worked for me, but I've never found the proper form comfortable. I've had computer classes up into my adult life.

With a good chair (my Herman) and wrist rest (a wood block) I've had 0 pain and work at my computer 8+ hours a day. I never leave my desk with any strain.

Hell almost every engineer I know doesn't type properly. For me, the real problem is I always tuck a foot under me and sit on it. 😂
