> we have developed a game designed to specifically challenge aspects of cognition that tend to decline with age and that are probably needed during foraging. In the game, players spatially navigate and complete attention and memory tasks while cycling at a moderate aerobic intensity level.

Sounds interesting and potentially fun. And it might provide more motivation for exercise. Startup idea...

Not silly at all. You could even relate the suicide of lower status males to this kind of mechanic. Or the grandmother hypothesis about why women have a menopause.

Those seem to contradict. Lower status males would be striving for a chance reproduce, or having reproduced would need to work to elevate their offspring's status.

The idea is if you've lost the race, let your genes that are carried by the winners take your share of resources. That way your genes win anyway. The individual organism is a lottery ticket.

https://www.ncbi.nlm.nih.gov/pubmed/10838463 I'll take my billion dollars in twenties please. Anabolism and catabolism are constant and simultaneous processes, even on a cellular level.

Where does it say anything about people growing muscle when catabolic or losing fat when anabolic? Just because the processes don't happen simltaniously, doesn't mean you can't gain more muscle than fat (or gain more fat than muscle) or lose more muscle than fate (or lose more fat then muscle), I never said the two were done at the same rate, just the body will gain simultaneously or lose simultaneously...but the bod…

You've moved the goalposts IMO, from the idea of being able to simultaneously gain muscle and lose fat with any particular diet and exercise regimen, to being able to simultaneously gain muscle and lose fat at any particular point in time. The former being what everyone means when they say they lost fat and gained muscle, the latter being a mostly useless concept.

But that study does implicitly contradict even the latter. The subjects were fed hypocalorically and had a net negative change in weight, yet gained lean body mass, implying at least some of the lean mass gain was fueled by metabolizing stored fatty tissue.

Is there a scientific way to distinguish evolutionary biology from bourgeois ideology?

Last I checked, Socialists were the ones who tried extremely hard to get everyone to be physically active. It was the Machismo Cuban Revolutionary who fought and won against decadent bourgeois ideology. Not the Sedentary Cuban Revolutionary...

If you're like me an dread the monotony of working out give climbing a try! Every climb is different which keeps the workout fresh and exciting and it works out every core muscle group.

It's infested with techies too.

I'm not sure about what you mean but a lot of completely made up "popular science" seems to be easily sold as evolutionary science. "Some people have longer ears than others. Maybe they were better able to hear predators and avoid them and therefore theirs genes spread further..."

Yeah, so much of it is made up just so stories, and those stories usually flatter the ruling class. It’s fashionable for CEOs to work out, so of course there’s a story about how it’s evolutionary biology reason that makes people smarter or whatever. That article was pretty short on experimental evidence.

I'd love to know if there's an above average tendency for those interested or working in the technology field also have a history with endurance related sports. I know a lot of really talented developers that are into biking/hiking/running.

I guess many of those sports are easily quantified, enhanced using technology (eg. bike computers, maps, running apps), and accessible without the need to be part of a larger social group.
