Actually, this was tangentially addressed. It specifically mentions the fact that we are getting less bright light exposure today due to our increasingly indoor habits (versus historical contexts where humans typically worked outside more), as well as the decrease in physical activity due to the changing nature of work as well. Furthermore, it specifically highlighted the disconnect between physical labor and reward (it called it "effort-based rewards"), or in very crude terms, we run to run these days, instead of running to catch our meal.
There's certainly a good deal more to the topic you brought up as a whole, but those were a couple of interesting points from the article that I thought it addressed.
