That’s a bit harsh. 57 here and my forearms, elbows, and wrists are f…ouled up without an ergonomic split keyboard and some other accommodations. Bodies are different, and if this guy is a rock climber, that might have something to do with it. But flat, tight keyboards give me tendinitis in as little as a day. I can’t even use my laptop without an external keyboard, which kinda defeats the purpose, but it’s what work gave me and it’s more powerful than my current, out of date, PC.
I climb and the typical position at workstation of hands pronated + shoulders forward sucks for postural health. I currently am dealing with bilateral proximal bicep tendonitis from excessive climbing and even being at the computer for a few minutes aggravates it. I wonder if it's possible to rig something up to be able to type in a supinated hand position and if it would be not super infuriating.
