Super-aged people have a strong appetite,

"Super-aged people have a strong appetite, especially those who love meat. Mina Kitagawa (aged 115), the oldest living person in the world, worked at a farm and enjoyed beef until she turned 100. Shigeyo Nakachi (aged 115) also ate three full meals a day and reportedly liked chicken and beef. It may seem surprising, but 60 percent of healthy people consume animal protein such as beef and dairy products every day. Failure to get the amino acids needed from protein leads to brain substances that deteriorate cognitive function and accelerates brain growth in older people. Some studies suggest that vegetarianism rather increases the risk of stroke (a disease that blocks blood vessels in the brain)."

"In Japan, there is a word '老害' (Rohae). It is similar to 'Kkondae' in Korea, which refers to an elderly person who gets angry at others, gets annoyed, and starts complaining." Elderly people with old brains are self-centered and do not care about others' eyes, causing inconvenience to others. Such behavior is caused by weakened function of the frontal 野, which is the frontal lobe, and the emotion cannot be controlled."

"When we looked at the characteristics of a centenarian with a healthy brain, we found seven main characteristics. The first was a pleasant meal. Tatsumi Fusa, who is currently the oldest living person in Japan (115 years old), is lying down in a nursing home but habitually says, 'Bob, not yet?' Eating three meals with a strong appetite lowers the risk of old age. Second is a warm house. Cold rooms result in constriction of blood vessels, which raises the risk of dementia. A study at Keio University in Japan compared a house with a house with a winter temperature of about 5 degrees Celsius warmer than a person with a brain 10 years younger."

"Maintaining indoor temperature of 8 degrees Celsius or higher is good for your brain's health. People with young brains are curious about new things and constantly challenge themselves, and participate in various activities as they are 'rich in taste'. Having a pet is also helpful for brain rejuvenation (回春). Many people think that not needing a notebook is not necessary after retirement. However, I think that what one must use after retirement is a notebook. Handwriting in a notebook improves cognitive function of the brain. It is well remembered because it is input while moving the body and stimulating the five senses."

"There is a way to keep your brain young even when you talk. You use onomatopoeia such as tangtang, whiik, tadak, etc. Even if you use it without much meaning, it has a significant impact on your brain. It is the same reason that athletes use onomatopoeia a lot. This is because if you use onomatopoeia while exercising, your body's movement changes. Shouting onomatopoeia can give you commands in your brain and exert your strength to the limit of your muscles (shouting effect)."

"I'm tired, I'm bored, I'm tired... These negatives exhaust the brain. If you've come to say these negative things, let's put a 'but' on the back. It's like, 'I'm tired, but I worked hard today.' The brain mainly remembers the last information, so 'I worked hard' remains in my mind. It doesn't seem like a big deal, but it's so effective that I saw a person whose life changed with the three words 'but'."
