Ehhh, not so sure about that. I was really good at FPS games (played counter strike for some 10 years), and I can't stitch for the life of me. My mother who is in her late 60s however, oh boy can she stitch and stitch fast. She can thread things well too - Last thanksgiving, we were doing some threading with the turkey, and I was amazed at her threading skills. I tried to imitate her but just couldn't.
Not sure. Don't game use only 2 of 5 fingers on each hand excessively ? ( Thumb and Index)
Suturing is not the only thing a Surgeon does...
But given the way games also tend to be addicting, I wonder if it hurts people's drive/motivation (on aggregate, not per individual) as much as it helps people's finger dexterity.
I often wonder if certain sports actually do a better job training dexterity, short of focused practice on specific tasks. Or knitting, or juggling, or... heck, even cooking.
To think of it now: I think boy scouts really are a great organization, to be teaching kids how to tie knots and survive in the outdoors.
I wish such a thing existed for me to attend as an adult!
