The way I explain it to my patients is that our neurons don’t regenerate. They make connections with each other and that’s it. If you don’t use your brain, they make fewer connections and, if one of them dies, you’re gonna miss it, because that was the only one that knew how to do X. Now, if each one of them has many, many connections, you won’t notice the difference when one of them dies. The others pick up the slack.

As of 2024, 45% of dementia risk factors are modifiable. Relevant to this conversation, 5% for less education and 5% for social isolation.

We absolutely are going to see the reflection of this, but it’s gonna take decades and it’ll be too late. So, for the love of your brain, pretend that it’s a muscle and make it work. People complain about “when am I ever gonna use this maths formula in my life?” You’re not. You’re teaching your brain to think logically. Those sinapses will be there for when you need to figure out your week’s schedule. English classes taught me how to interpret data and how to convey it in this text so it’s clear and you understand what I’m saying, not because I needed to justify why the curtain is blue.

Make your brain know how to do different things. Logic games, puzzles, taking care of a garden even if small, planning a church’s event or birthday, learn a new instrument, learn a few words in another language, look at a calendar every day, do some manual labor if possible. Do not, I repeat, do not let your brain get rid of sinapses by letting AI do everything. Your brain uses 20% of your body’s energy — do you really think it’s going to maintain connexions that aren’t in use?

Most cases of Alzheimer’s are sporadic, meaning no family history. Family history of a first-degree relative with Alzheimer’s starting before they were 80yo increases your risk in 2-3x on average.

Use a calculator.

Calculators are very good. Calculators operate on logic.

LLMs operate on pattern recognition. Like you. You at your fuzziest. Because when you rely on pattern recognition for maths what you're doing is a vague approximation. There are various ways you can train your brain to be better (part of the reason learning times tables by rote is effective is it hacks this), but your pattern-recognition, surface level maths is for going, 'That's what five things looks like. There was about five things over there and now one of them's gone. There's probably about four of them now. because that's a pattern I am familiar with in those circumstances.'

This is a quick and effective method for looking at shit and summing it up, but it isn't *reasoning*. And because the reasons why an answer is correct or incorrect are no part of delivering the answer, it can very easily be wrong.

This is like the well-known phenomenon among logisticians. Trained professionals who are Good At Logic frequently get things wrong in tests when asked to give their initial, instinctive response. Because it relies on pattern recognition, not actual reasoning. Good for counting lions on the savanna, shit for calculating your tax or confronting the Monty Hall problem.

And then I went to the USAmerican Midwest

Rains frequently, but the worst is like standing under a bathroom shower. Genuinely inhospitable rainstorms are uncommon.

Along the coast, it's pretty easy in most areas to walk to at least one store, or else there's usually a bus or shuttle available. There are sidewalks and bike lanes everywhere.

It's a temperate boreal rainforest, so while there are many freshwater lakes and rivers, they're usually pretty cold. The biggest danger is typically getting caught in a strong current, and the most dangerous animals in swimming distance are on land.

Earthquakes happen almost every day, but the vast majority go unnoticed. Buildings are designed to withstand bigger seismic activity, so unless it's a 5 or higher it just kind of feels like having low blood sugar for a second. There are no tornados

Rural Illinois, USA:

One minute it's sunny, then ten minutes later that distant smudge on the horizon has swallowed the entire sky in black clouds and the water is coming down like waterfall and you literally CANNOT SEE. Then there's a crash like cymbals and you need to get indoors because the thunder and lightening are on TOP of you

No sidewalks until you are in the smack dab center of town, which is a three hour walk or twenty minute drive from wherever you are.

There aren't many natural bodies of water other than small ponds and creeks, and because the environment is so much warmer, those are filled with snapping turtles that can grow bigger than a nine year old child and water snakes that are incredibly venomous. These are paired with leeches and mosquitos for that sweet umami flavor.
