Very interesting.
Dean Karnazes, one of the worlds best Ultrarunners, ran 50 marathons in 50 states. He finished all these races in 1 year!!
We are undoubtedly capable of extreme exercise volumes.
Despite our abilities, we are turning into One of the most sedentary beings.... We may even start hibernating one day, like bears... lol
I pretty much already do!
Ha ha ha, we are all in the same boat. Our jobs, entertainment and social lives are on our mobile phones... We only need to move our thumbs.
I'm waiting for eye-controlled lifestyles, bliss!
