I don’t get it. The linked article says that sitting for a long time makes the brain shrink, controlling for exercise. You say that everything is degenerating. That’s obviously correct but a red herring, no? We could say that the issue is not lack of exercise for people who age but rather that they age. No, because exercising will help fight against the degeneration. > But since we have more fixes for physical degeneration than mental degeneration, we see most sedentary people kept alive through medication and constant surgeries well into their 80s and 90s while there is nothing much to reverse whats happening to the brain. Doesn’t regular exercise help the brain as well as the rest of the body? The brain is part of the body. Now in addition the OP says that sitting is bad for the brain. Controlling for exercise. > Having worked for a while at a hospital, I feel people who really haven't lead active lives or are just naturally less active or don't like too much activity fall into this trap, where the medical system will keep them physically alive for few decades longer than in the past. They need to be told this could be a trap. Instead we keep them alive, let their brains degenerate and study them like lab rats. Since the article is about sitting and controlling for exercise I’m gonna assume this means sedentary people as in having been sat on their ass a lot. Irrespective of exercise level.
