alt Hacker News> mitochondria, which process energy within cells, showed a significantly decreased capacity to burn both sugar and fat in healthy individuals who get less than the recommended 150 minutes of exercise a week.
150 minutes a week is about than 22 minutes a day. Like 11 minutes twice a day. This looks like a really low effort to rid oneself of the risk of early decline.

A lot of people who use a car to get around will spend most days doing literally no actual exercise. For someone who lives in a more walkable area, 22 minutes of exercise is just living live normally without actively "exercising".
A studied showed that elderly asians have better health outcomes that their western counterparts in part due to their practice of sitting on the floor. The added exertion of standing up from the floor rather than a chair makes a material difference in their health.
I've seen studies like this before. They'll suggest that as little as 15 minutes of exercise significantly improves health in some group they studied. My initial assumption was they added 15 minutes of additional exercise. No, they studied people who did literally nothing. Then had them exercise 15 minutes a day.
As you might guess, their outcomes improved greatly.
