Deepen your existing spiritual commitment.

Walking is the only way proven to stave off cognitive decline - it works.

So learning to play a new instrument, learning a new language - those sorts of things will pay dividends for years or decades to come.

The gym and the treadmill is a good idea. But the problem is we spend so much effort in marketing messaging, deluding people into thinking if you get on your treadmill or you go to the gym, that's what you need. People who join a gym, the vast majority of them have quit within nine months and almost all of them have quit within two years. So if it's a longevity strategy, does not work.
