Unsurprisingly, exercise helps health. What’s surprising is the degree to which this is true. We evolved to move, not to sit in front of a computer for 8+ hours per day. Yes, exercise is difficult and can tempt procrastination, but for the small time investment required, the results are noticeable. One recent study, although in mice, is especially impressive because exercise appeared to thwart aging even in genetically weakened mice. 1 2 I aim to walk (or do other exercise, like tai chi) for at least 30 continuous minutes at least five days a week. Most weeks I meet that goal. Some weeks I don’t. I don’t beat myself up over it — I just make sure I go outside and walk around the next day.
