Don't have access to the paper, but the abstract seems to at least confirm OP's

I... Don't ... see what he said? Did he delete it, what happened?...

I am a heavy gamer and guitar player, I have used a computer regularly about 4-6 hours minimum for 10-12 years off and on (every other year at most). As for guitar, well.. Just try to play one with dedication in the proper way. Your hands are morphed from the task.

Granted, I'm not biologist and don't know what this does to an individual long-term, but its seldom researched - especially long-term - and only a handful of people have experiencede 6-8+ years of dedication. Nevertheless, a biologist or physician will never know what goes into either of these specific tasks.

T;dr it takes experience.

On top of that, going further and further in your skill will make it less impactful, sure.. Yet the average writer doesn't experiencee this. All guitarists have hand issues to some degree. All high-skill pro gamers have a limited career physiologically; they absolutely cannot do things forever. Pianists and violinists are other notable examples. My hanwriting is bad, and I'm a fan of handwriting, artwork, calligraphy at best.

ELI5: Males definitely do more wrist/tendon/ligament tasks than females, barrnig typists which definitely do not have gender/job bias; their peak is definitely not sustainable, and that's not anectdotal because its so prevalent..

Imagine you're lifting boxes for a job all the time, regardless of gender. You'll be stronger from it. Same goes for human manufacturing; it takes a lot of dexterity to be consistent. Doesn't last forever. Young humans are chosen for certain tasks due to that flexibility. It has nothing to do with gender, it's merely profession-based, and I wish people realized this for the sake of that bias,

Only posting this because there's a lot of "Male vs. Female" genetics involved. News Flash: That's not how the body works. Some people are talented, others simply have a typical maximum.
