Let's walk.

I don't like walking but after reading this book, it seems that I have to change my this custom.
This book (よみがえる脳 )--{a brain continue to change=my translation} was written by Dr. pharmacy ,Satoshi Ikuta.(生田哲).
Let me introduce this book.



According to this book......
Formerly people believed that the aging people's brain doesn't produce  new nerve cells. But even the brain of the age from 50 to 70 makes from 500 to 1000 nerve cells per day. They are produced at hippo campus or cerebral cortex and move to the proper place and become mature nerve cells and are set in the network of the brain.




Nerve cell,or neuron.

Hippocampus in a brain and sea.

Do you know how to make a clever mouse?
The answer is to make them run. After running, their hippo campus volume increase.
Human is same as mouse. By excise, blood carries lots of nutrient and oxygen to make cells to a brain. And new nerve cells are born in area of frontal lobe hippo campus, temporal lobe.
And signal (learning, experience etc) have to reach that area to make cells survive and to make them set in the network of
a brain. Because brain cells are not used die.
So the way of the effective studying :
Excise is the first ---------to make lots of new nerve cells.
Studying is the next ----to set nerve cells in the brain network.

Not a mouse, many mice are running----this is better environment for brain.Animals use their brain to survive.

When we excise, four peptide hormone( BDNF, IGF1, VEGF, FGF2 ) are emitted in our body. These enter the brain and become nutrient to raise nerve cells. BDNF makes a brain memorize what we learned.
The others work similarly. When we are aging, the emission of BDNF decrease. So excise make the speed of death of nerve cells slow.

As excise, it's proper to walk of 30 minutes/ day or jog of 1.6 km/day.
It seems that I can walk for 30 minutes or so if it's ok to walk slowly.





Jogging, swimming, cycling, walking etc are good for anti-aging way.

Also, excise is good for depression. Because when we excise, the brain emits noradrenalin, serotonin, endorphin, dopamine etc that are good for depression.

The brain assigns much section to a field that we use a lot in the cerebral cortex. Soa  brain map expresses our life. When one of our ability rises by physical-training, our brain map change. Then does it also occur by mental-training?
When we excise piano lesson in our mind, we can change our brain map.  Having interest and concentrating make our brain map change. But we need training to concentrate mind. This mental training is meditation.
Buddha got "release from worry or stress"(enlightenment) by mental training. The area control feeling in the brain of people who meditate expand. This may be reason they think positive or have stable feeling.

 Thank you for reading a long sentence.

Sarah, I finally got to know why you were keen about walking these days with your sun visor. You did not like walking so much until recently.
Thanks for your helpful and encouraging report!
I am happy to know that a possibility is left in my brain cells to improve my English though it was too late to start learning another language. I will try to walk much more!

Sarah, thank you for this summary of the book. As Tomoko said now I understand why you started walking all of a sudden this year.

Our body parts and mind are so mysteriously and miraculously made up, naturally adapting and developing by themselves.
I can have a gleam of hope that my mind could be clear and sharp and my body fit and trim as I age by taking exercises, walking, learning English, plus meditation and relaxing time in between.

"30 minutes' walk a day" sounds easy but I know it's easier said than done. So I sometimes take a week's walk all one at a time on Sunday.
From what I heard before, either way will do.
Am I wrong?

Anyway your post assured me that walking is good in every respect.

Sarah,
Thank you for your useful information.

Around ten years ago or so, I got interested in the brain. But unlike you, my interest was about psychic power. And I got some conclusion -people with supernatural power are using their brain capacity more and more. Our brains have immense possibility but we don't use them well, use only 10% or so.

Walking and meditation sound help boost the capacity of the brain very much.Maybe if we keep walking and practicing meditation everyday, not only it makes us healthy but gives us different ability・・・too much watch SF movies??

Thank you for this interesting information from a book, Sarah.

I had ears' problem last Autumn and it was slow to recover, that sometimes irritated me. Finally I found a good doctor for me, a little far from my residence. However to walk there seems good for me. Your summary made me confirm it.

Thank you for comment,Redrose.
Yes,I can't go out without my sun visor. So I don't like going out in Summer.
I think it's not late for you to start learning something. You are serious and you can concentrate to do something.

I think you are worrying and busy for your acquaintances in devastated areas. But take care of yourself and asthma.

Thank you for comment,Stardust.
I heard before that walking is good for us. But I didn't know the good reason. So this book taught me it by a scientific method and I was convinced. Thanks to invention of equipment that scan in our brain, we may know more things.

Thank you for comment,Cosmos.
I also knew walking is good for me logicaly for the first time.
Does "either way will do" means "30 minutes walk a day" and " a week's walk all one at a tine" both are good? I couldn't find this point in the book. But you walk for about 4 hours on Sunday?
Awesome!

Thank you for comment, Snowwhite.
I don't know what about psychic power is. But if supernatural power include, for example, shogi players or person who has perfect pitch,mental arithmetic etc, I can understand. Maybe a equipment that scan their brain will prove.
If we are young, we may be able to have different ability but our hippocampus starts to diminish from about 30 years old, according to this book.

Thank you for comment, Haricot.
I sympathize with your ears' problem. I occasionally have it,too. Take care,please.
For walking to the doctor's, don't overwalk,please. Because I don't know if walking is good for ears' problem.
