Why, as a rehabilitation medicine specialist in the neurology field, have I written more about regular exercise than about rehabilitation? It's because it's easier to prevent problems before they occur than to restore the brain to its original state after it's been damaged or diseased.
It is much more economical and effective to keep the brain from getting sick or injured.
How do you prevent brain disease? It's not that big of a deal.
If my body is healthy, my brain will be healthy too.
So, all you have to do is make an effort to keep your body healthy.
And this effort must begin early, before the body and brain become sick or old.

The answer lies in 'fun'.
If you find running fun, that's the end of it.
Even if you try to stop it from the side, it will eventually run.
If you don't have time, make time and run.
It has already been proven through numerous studies that when you find a hobby fun, you maintain it longer and enjoy it more deeply.

But a health checkup is not a test.
Rather, isn't it to accurately understand my usual appearance?
Even if you prepare thoroughly and pass the standard, it is of no use because it is not the original appearance.
It's like looking at a face in a photo that has been beautifully edited with Photoshop and feeling happy that it's the real me.
It is very dangerous to miss the opportunity to filter out abnormal findings due to a sudden attack.

It takes decades to clear a forest, but only hours to burn it down.
The brain is the same.
To keep your brain healthy, you need to consistently nurture your body and brain together throughout your life, but brain damage from accidents or illness only happens in an instant.
Just as broken trust is difficult to repair, and it takes a lot of effort to restore a burned forest to its former state, our brains are also difficult to restore to their original state when damaged.
Except in cases such as mild concussions, severe or repeated injuries are often irreversible.
I see all the time in my patients what happens when a damaged brain cannot be restored.

Various research results and actual data from world-class marathon/track and field events show that there is no significant correlation between landing technique and marathon time.
You can also see that the most common landing method used by world-class marathon/middle-distance track and field athletes is rearfoot.
Rearfoot is the most common running landing.
And there are a lot of athletes who are excellent at running with a rear-foot landing.
The claim that you need to run midfoot to run well is difficult to substantiate.

This perceived-felt vulnerability is what allows us to take control of our health and take action.
If your self-awareness is inaccurate, you run a very high risk of not starting health care in a timely manner, and only becoming aware of it after your physical functions have seriously declined or you have been diagnosed with an illness.
The bigger problem is that by then it's irreversible.
So, it starts with creating an opportunity for self-awareness before it is too late.
I need to create opportunities for myself to test my body's capabilities and limits, even if only occasionally.

What made him, who didn't even recognize his family or what he was doing in the hospital, walk after three years? The concentration he used to chase a tennis ball, the strength he used to swing his racket against the ball's resistance, the determination he used to play, the stamina he honed in his youth, the grit he used to endure arduous training, the determination he used to win.
Those things came to mind for me.
Whether it's grit, will, habit, inertia, physical strength, or whatever, lifelong habits are engraved in the body and soul and are exerted as strength in times of crisis.

Even for diseases that are far removed from exercise function, such as dementia, cancer, diabetes, high blood pressure, obesity, and depression, exercise is an important treatment.
Exercise is just as important and effective as dementia medication, anticancer drugs, or surgery.
The problem is that no one can do exercise for you; you have to do it yourself.
That's why not many people can properly use exercise as a treatment.
Only when the patient is physically and mentally prepared to exercise on his own can exercise be used as a medicine when he becomes ill.
However, if you live a life that is far from exercise for a long time, you will end up in a state where there is 'no more medicine to use'.

Humans survived the harsh environment and competition for survival on Earth by running for long periods of time using aerobic metabolism.
The memories of running for at least a million years remain intact in our genes and our bodies.
Our bodies are designed to live that way.
This also means that if you don't live as designed, problems will arise.
