I believe that we'll see a lot of "x is good for your brain" news (with X just being any activity that doesn't involve a screen), now that attention spans are so short and everyone feels like their brain isn't the same anymore.
The same way we got gyms when people realized physical inactivity is super unhealthy.
What if we took the idea of two minutes of hate session from the dystopian 1984 and made it available all the time. Everyone could carry in their pocket their own personal two minutes of hate that they can have any time they want as often as they want. Orwell never dreamed so high
We all have that already, it's called smartphone sadly.
It works with whatever political direction you lean on, which stance you have on two or more genders, which religion you love or hate, which gaming platform you prefer, how old you are and many more "divide and conquer"-topics.
It'll be difficult to replace because it's so effective already...
What percentage of people are neither of the simple common XY nor XX chromosomes?
It's about as many people as there are with red hair. If you don't include chimerics it's about 0.25-1.7%, if you do include twin chimerics it's 8%, not including mothers micro-chimerism.
Probably shouldn't be having those Kenyans (Kalenjin) competing in marathons either. Completely unfair advantage.
Funnily enough, my bird watching does in fact involve a screen — the electronic viewfinder on my camera[0].
Jokes aside, there is a very definite difference in how my brain "feels" when I'm walking around, camera in hand, looking for things to photograph. It's like I'm in a different "cognitive mode", for the lack of a better term. It's not just about being present and in the moment, but about seeing the world around you from a different perspective.
I think it is slightly different than that. I think it is more about active brain activity versus passive. Learning how to play Riichi Mahjong (e.g.) would likely show a similar effect. A lot of people push brain puzzles as a tool against dementia, etc. but it is only helpful when learning a new puzzle type. Once you over learn it, our innate pattern matching takes over and you start playing on auto-pilot, it stops "rewiring" your brain. Just sitting on the couch binging streaming or swiping through shorts is likely to atrophy your brain.
Obviously being out in nature has other mental health benefits. The key thing is to keep learning and stay curious. Drive to some new nearby town on a weekend and learn about its history. Learn a new hobby like full f-stop photography or learn how to bake or cook (learn all four base sauces). Take up board games and explore all the different kinds of experiences they provide today.
That's great! I think anything that's not passively consuming a screen will be known as "good for your brain", the same way that regular food has become known as "health food".
Eschewing eating ultraprocessed, factory-made food is now seen as a deliberate health choice, even though it used to be the default. I think the same is happening with the brain.
Reading a book is now seen as some erudite choice. Having a hobby like knitting, birdwatching, etc. will be some kind of "good for your brain" activity. Things that used to be the only option are now "healthy choices".
Oh please, this is Internet nonsense. Google tells me:
> Psychologists and neuroscientists find no structural decline in the human brain's ability to focus. Sustained attention limits remain largely unchanged.
A lot of, "birdwatchers" I see travelling to remote parts of Scotland and other places in the UK are generally wealthy retirees, with nice kit (Rab clothing, telephoto lenses, VW campervans).
Cognitive decline is shown to impact disproportionately on less wealthy people. So is there a trend with economic wealth and outdoor hobbies like birdwatching? I'd hazard a yes.
On a side note, the Merlin bird ID app from Cornell University is great.
Not sure, but this is definitely a thing - the "a single glass of red wine a day is good for you" claim is pretty likely more about how people who can afford daily wine are probably wealthier people with better access to healthcare, not that any amount of daily ethanol intake has a therapeutic effect. https://jamanetwork.com/journals/jamainternalmedicine/fullar...
For what it’s worth, this article cites a longitudinal study done by German researchers.
They basically installed a bunch of bird feeders outside nursing homes to see if watching birds improves the health of the elderly people. The researchers concluded that it did:
Nursing home staff were the first to see the difference the birds made. "For weeks, they haven't seen a smile on [a resident's] face, and then they see the smile," Kals says.
Some of the memory and concentration improvements are evident after just three to four weeks, Kals says.
It seems that they used the following bird feeder in their study:
You have quite a biased sample because most people are not going to suffer going to remote parts of Scotland to look for birds, so you are only seeing the more devoted birdwatchers.
Birdwatching can still be enjoyed in most places without needing to travel far. Birds are less active in bad weather so you don’t need expensive outdoor gear, and in many places there will be freely accessible nature reserves with hides in which one can sit in shelter to watch birds.
The highest quality glass is going to get pretty expensive (camera lenses can get to the region of $20k; binoculars $4k or so) but there are also much cheaper options and often these can be quite reasonable: you don’t need to take photos of birds; a superzoom point-and-shoot can work great; more expensive binoculars make a bigger difference in low light and if you’re young (older people’s pupils won’t dilate as much so bigger objectives at a lower magnification won’t be a huge help).
I feel like mostly you’re observing that rich people spend lots of money on their hobbies and not that opening your eyes to look at birds is some expensive exclusionary activity.
Even better, older Nikon DSLRs are now cheap with many F-mount lenses being incredibly cheap versus buying new mirrorless gear and lenses.
M43 systems are also excellent for bird watching given the 2x crop factor, and diminutive size of lenses verses larger sensors. Older M43 camera bodies are incredibly cheap versus new equipment. M43 combined with modern LLM-based denoisers means that even low-light photos with higher ISO really can end up looking incredibly good.
I have a Nikon P1000 while it doesn't have the best image quality does make up for it in having a truly remarkable zoom: 24-3000mm. Just the thing for taking pictures of birds and then working out what they actually are at my leisure.
Birdwatching is truly one of the cheapest possible hobbies you can have. Yes, you can make it expensive if you're committed to photographing them and traveling to remote locations to find "life list" birds, but that's not the vast majority of hobbyists.
I'd say a lot of activities like this can be done for cheap or free. Taking an elderly person to the park is free, it just costs time. Binoculars are ubiquitous, and bird books are a dime a dozen in your local charity shop.
The critical thing is that these people need a hand to get out of the house or do any kind of activity. And I think that's partially behind a lot of ailments that affect the elderly, they don't go out, don't get physically, mentally or sensorily stimulated enough so they atrophy in all those areas. On top of age related conditions like senility, parkinsons, altzheimer's, etc of course.
I'd really say the opposite - birdwatching cuts across socioeconomic classes surprisingly well in the UK. At least the subarea of bitding which is focused on rare birds.
> On a side note, the Merlin bird ID app from Cornell University is great.
Do you know how it compares to iNaturalist? I'm not a birdwatcher, but I have iNat on my phone and sometimes use it to identify birds, and it seems to do a great job.
I have tried both. Merlin is best for bird watching. It does not ask to upload any data. Just start the recording, it listens and let me know what is the bird is. Done. It only uploads, IF I want it upload.

Perhaps we need to provide opportunities for less well off people to access nature? It might have a positive cost-benefit. And design care homes around gardens? 'forest bathing' is apparently often recommended in Japan based on studies of blood pressure and other physical indicators.
Munlochy: if you ever saw a geezer wearing an ex-army parka, builders safety boots with Opticron bins it might have been me. I don't get up there often enough to warrant the pricey stuff.
I'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.
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.
> > 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.
> Maybe by comparing the comparative cognitive of twins, one of whom has a hobby and the other doesn’t?
It seems also just enough to say supporting people to have a hobby if they're at risk of dementia and don't have one is important to meeting their social and health needs.
I might be being too cynical.
I wonder if there is some funding arguments, I.e. if it's for their health and insurer may fund it.
If it's for their social/cultural and general wellbeing it might be out of their remit somewhat.
Many hobbies do that for you. It’s important to engage with something that you like and use your brain. Also, part of the equation is to keep on moving. If you take daily walks and engage in a desk bound hobby it’ll likely provide similar benefits discussed here.
If you haven’t seen it, Listers (https://www.youtube.com/watch?v=zl-wAqplQAo) provides a great glimpse into what competitive birdwatching looks like. It’s nothing like casual birdwatching.
I watched this is and it's such a great documentary. I really want to take a year now and try to get at least in the top 25% of birders for the year. I was into casual birding before (it's my favorite thing to do when traveling to a new place, just wander around the area and spot local birds). But now I'm loving the idea of these monthly or annual "competitions"
I can’t recommend this documentary enough. The algorithm dropped it onto my YouTube homepage one day and I wasn’t expecting to watch more than a few minutes but I was drawn in immediately.
I don’t consider myself a birder but I’ve got into nature photography in recent years and it’s such a joy to get out for sunrise or sunset and to come home with a special shot.
There's the "always on" type of birdwatching as well, that allows you to recognize the birds you see and hear in the course of ordinary life. No patience required, just practising staying aware of peripheral vision and sounds, but equally rewarding when you are lucky enough to have a chance encounter.
This feels if nothing else quite analogous with default mode network, i.e. brain regions which are task-negative (or task-neutral).
It seems that the literature supports the intuition that to meaningfully relax (i.e. exercise the brain with fewer pressures of time, success or similar, and with a relatively low information bandwidth) is really good for cognitive health. And it's very good to destress, which we can all benefit from!
So even if there are more cars than birds outside my own window... I'll make sure to spend a few more moments each day by it :)
Erik Wing, who led this research at Baycrest Academy for Research and Education in Toronto, Canada, compared MRI brain scans from bird experts to those of novices while they identified birds. He found that expert brains were wired differently in regions important for functions like attention, visual perception and visual recognition.
The study only (?) looked at the brains of birdwatchers, the paper extrapolates the study to make assertions about the brains of active subject experts in general.
More likely socialising and long walks in nature slows cognitive decline - how do you control for this from the results to make the birdwatching part relevant?
Sounds to me that nature (and the animals) is the thing that slows cognitive decline and so on and so forth. Not birdwatching per se. (I didn't read the article, but having studied psychology, I am assuming with confidence that there is a confounding factor that makes it look like birdwatching is the _thing_ that slows cognitive decline.)
In some ways they do, but actually going out into nature, smell different air, get aun on your skin, wind through your hair, see all around and not just a flickering screen and interface with reality with your whole body, not just eyes staring to a square and hands moving mouse and keyboard .. seems even more beneficial in activating the neurological system in the body.
I knew it! Those 30 and 40 somethings are always up to something. You never see them, never hear them, but here they are slowing their cognitive decline. They are clever little rascals. They're just like the species they're watching.
But I created a set of amazing binoculars with automatic AI age detection via radar for the small friendly price of 39.49$. Looking for a bird watcher? Get the SilentBirdWatchDectector 3000 and slow your cognitive decline at double the rate.
Don't watch the birds, watch the bird watchers instead. They may do something interesting.
look, look! A millenial father observing bird species in an effort to stave off cognitive decline, rarely seen away from his burrow and demanding offspring, we can see from its markings that this one was once a hipster, note the foliage pattern about it's left radiocarpal.
"The findings don't prove whether structural brain differences are the cause or effect of birdwatching expertise."
Not a big surprise that this observation proves exactly nothing as there are thousands of other factors they could not control for (and apparently didn't want).
"Her team's findings have prompted German health insurance companies – who, among others, initially funded the research project – to invest in setting up bird feeders and viewing areas in more than 400 nursing homes across Bavaria. "
This is kind of hilarious and I would not believe that if it weren't Germany, a country that intentionally destroyed its nuclear plants capabilities in order to burn Russian gas and emit CO2. Obviously in the name of reducing CO2 emission.
