Interesting research but very early stages. There's a good chance that this isn't really specific to bikes, but more generally applies to the benefits of people enjoying hobbies and a good quality of life translating into a better psychological state, which is known to affect health outcomes in a myriad of ways specially related to brain function and hormones.

Interestingly, the data also shows that mixed-walking is associated with reduced dementia as well... and I find it a bit confusing that the authors are lumping driving and public transit together in the nonactive category because public transit usually involves a good deal of walking too without people categorizing it as a walking mode of transport.

Beyond separating public transit from driving, I think major factors to control for are: 1) how often these non-commute activities happen; and 2) what's the stress level of that transportation mode. With those three things in mind I think it would clarify why would walking be associated with worst outcomes than nonactive...

It's done wonders for my legs. My brain, on the other hand...

Strange story.

as a hobby

So drive for fun rather than just as a mode of transport?

Just remember to wear your helmet.

No, thanks.

Also, people cycle a lot in the Netherlands and it has one of the world's highest rates of dementia 🤷‍♂️

Wait, this is a recent article? I (and Wikipedia) thought Vice has stopped publishing articles? (I aslo dimly remember them being bought by someone terrible but looks like I'm confusing that with something else)

I loved bicycling as a kid. I don't think I can find an under 100 dollar bike these days though.

Why is Vice still a publication?
