I've also seen articles saying there's a similar declining level of physical strength among men (measured by grip strength). I wonder if sitting at home all day playing video games instead of being outside running around reduces T levels.
"Running around" means several things, in context he probably means kids being outside playing. Like running around the neighborhood, climbing things, throwing things, etc. Not just being on their feet running.
Yup. When I was a kid there was nothing to do inside. We were outside most of the time, riding bikes, building forts, wriggling through the storm drains, built a gokart, biking everywhere, impromptu games with the neighborhood kids who were also outside, throwing rocks, climbing trees, all very ordinary stuff for the times. I even tried to build an airplane out of scrap lumber, much to my dad's great amusement. Using a hand saw would sure make my arm ache :-)
There are a lot of kids in my neighborhood, but I never see them. They're inside presumably playing video games.
