> Exercisers outperform couch potatoes in long-term memory, reasoning, attention, and problem-solving tasks I'm pretty sure the cause/effect is reversed here. It's more likely that people who are smart and have better focus/are less impulsive are more likely to take care of their health and exercise.
So how come Stephen Hawking isn't a mental slouch by now ?
What I'd like to know is how this boils down wrt work. If an increase in mental ability represent a greater work-done-per hour; But the cost is time spent exercising -> less time working (maybe somewhat compensated for other positive non-work benefits), Then what would be the perfect amount of exercise to boost productivity? i.e. would an hour spent exercising pay for itself in productivity boost?

That depends completely on how you define "strong". I think legs that can carry a 50 pound pack to the top of a mountain are "stronger" than a guy who can lift twice as much as me, but can't even run a 5K.
That's endurance, which is objectively different from strength.
Because last I checked, the english language was flexible, with multiple definitions for most words. I looked a few up for "strength". I did not find any dictionary that solely defined it as the ability to move heavy objects.

A single data point is hardly an argument.

inversely correlated I hope?
The term "inversely correlated" is a new one for me, since correlation is two-way, and, as they say, not necessarily causal.

Or weightlifting, squatting and deadlifting heavy on a regular basis will give you substantially stronger legs than any runner.
I'm not entirely convinced 'strong legs' are the causative factor in healthier brains. It is possible the researchers measured an artifact of people that do running cardio.
I go to therapy to manage my depression. I don't have a severe case, but it's bad enough that it affects my productivity at times. Once a year or so I'll have a bout where I am almost completely unable to function. The tools I use to manage depression are (wait for it) diet, exercise and prayer (or meditation, if you want to keep it secular). Exercise is particularly useful. Depression affects the mind, so it's diffi…
