I try to work 4 hours one or both days of the weekend when i have the chance. This way i can earn up some hours without, as mentioned, contributing negative to our project. I'll have a stress-free morning, usually a workout and then it's off to work. (Ok, and maybe some drumming on "Guitar Hero: Metallica" if i feel like it..) When i go home i'll still have energy and plenty of hours to relax and do whatever i want.

And, it's remarkable how much i get done when i'm left alone to concentrate and focus, without people distracting me.

They seem to have forgotten about the metagamers :)

Given that antioxidants neutralize free radicals, here's a test one could do to see if free radicals really are involved.

Take two groups of people. Group #1 are people who's on the paleolithic diet (stone age diet), with very high intakes of antioxidants and thus a low level of free radicals. And group #2 are on the fast food diet or something that's really low in antioxidants and thus have a high consentration of free radicals in their bodies.

I would expect to see more light from group #2.

Not necessarily, the first self-driving car to follow a ordinary car could do this at a safe distance, and self-driving cars following this one would just follow in a normal self-driving kind of way (1 meter behind or whatever). The lead self-driving car would then smooth out any errors made by the ordinary car, and overall make for a smoother ride for all. Then you would have eliminated at least a bunch of drivers and all their errors.
