Again, sorry for the low volume of post, response, etc. Not only do I have a new job (as a contractor) where it's very important that I impress everyone. And so I've been doing a lot of impressing folks at work...large reserves of energy in use. Second...I'm working with Agile experts who are both smart, more experienced than I am, and who think widely...So an awful lot of my intellectual energy is being dissipated at work. Third...my job at work is to nudge teams in process imporvement directions...and so I am, but it's again huge amounts of persuasion and education. And...in order to impress and make friends with my co workers, I'm posting on their Scrum blog. Besides...I'm still unpacking, putting together the trampoline, putting together our new pool, organizing the house, etc. Having said all that...here's something interesting.
My largest remaining puzzle on exercise was the question around running. Humans are clearly evolved physically to win the endurance contest. Our hairless state makes us clearly all about heat dissipation...which mostly means we can run down any animal on the planet over the course of 24 hours. In a 2 mile race, bet on the horse. In a marathon, bet on the human. But...we are just as clearly evolved to get benefit from short bursts of exercise...and from small amounts of aerobic exercise. What fits? Also...as a side note, I get tremendously fatigued walking about a museum...and what's up with that?
Here's the rough answer:
Humans are evolved for walking quickly after animals, with occasional bits of running. We are NOT evolved for standing about, nor for extenssive running. AFAICT, that pretty well handles my whole evolutionary puzzle.
Paleo food: Ruminants + Root Vegetables are the only large evolutionary sources of calories. Preference towards Ruminants.
Paleo exercise: Lots of walking. Some heavy lifting, some sprinting. NOT standing
