alt Hacker NewsI'm into ham radio which, as a hobby, skews to an older demographic. Does just having a stimulating hobby actually slow decline? Most of the fun of ham radio is learning - it never stops, there's always something else to discover. I'd guess that it's the learning, searching, and connections you make that provide the benefits. Unless being in nature is a requirement, but then you have plenty of retirees that go RVing - do they experience the same benefits? I doubt that's as intellectually stimulating as birding or radio. Maybe.

I think going out into nature adds more physical factors (ham radio and video games are both physically pretty passive hobbies) and more sensory input, which gut feeling says are overall better.
But generally speaking, hobbies are good. That said, I wonder why video games don't seem to be more popular as post-retirement hobbies.
I think some hobbies tap into innate abilities more than others. And those tend to show more perceptible and immediate progress and so are more likely to become a regular habit. As a human you already have a facility for recognising things in nature, it is how humans can find food and detect threats. Where as other abilities (like playing a violin) are far less innate.
For someone that knows nothing about ham radios can you give me a taste for what you mean by requires continuous learning from a naive perspective? It seems like any other radio technology that has not changed in decades.
Yes of course, anything the requires skills you don't otherwise use. In particular continuous learning is very helpful.
The challenge however is, is it that those who engage in such hobbies have decline slowed. Or are they able to engage in those hobbies due to not declining.
It's not possible to answer clearly without some randomisation and control which is basically impossible.
Still, it's reasonable inference that hobbies and work maintain cognitive capabilities.
