How do you know that your ancestors didn't have numerous orthopedic problems caused by constantly running down and killing animals, which resulted in drastically lower life expectancies than we enjoy now?
- oostevo 16y agoI don't; it was just a thought experiment. However, I did have someone with a Ph.D. in kinesiology (I think?) tell me that there's essentially no evidence of knee, hip, or back dysfunction in developing countries where people don't sit all day.
- corprew 16y agoOne of the interesting things you see in undeveloped countries is that people squat in a position that is hideously uncomfortable if you're used to using a chair. Here's a somewhat nutty article on it called "third world squat": http://www.t-nation.com/free_online_article/sports_body_training_performance/the_thirdworld_squat http://www.t-nation.com/free_online_article/sports_body_trai... but it is an actual thing that people and it makes for a different muscle development than chair-dwellers have.
