As a 52 year old regularly playing ultimate frisbee, in my own N=1 observation, sitting and sedentary life just leads to restrictions in movement. The more I sit the less easy it is to move afterward, especially getting older. I also see it in my elderly mother and the people around me the less they do the less they do.
Also, I see that the repetitive exercise that I do still leads to issues because only certain muscle groups are constantly strengthened while others lapse.
We can see this process she’s talking about accelerated when it comes to space travel, you know that thing that we’re not ancestrally designed to do. https://www.nasa.gov/mission_pages/station/research/experiments/245.html
As to the snarky comments regarding the phrase “ancestral point of view” just keep shooting anything down that doesn’t fit into your limited view. The medical industry will certainly profit from it. You also might want to actually watch the video.
I get that not everyone can follow the suggestions in this video due to illness, ability limitations what have you. But to dismiss this idea based on “not all people are able to move like she suggests” is nonsense.
