Discovering the "supernatural secret" behind the long life

Many have long questioned the "secret" of the long life of the old people, who sometimes cross the 100-year barrier, although many do not live a healthy lifestyle, as revealed by a recent Japanese study.

Researchers from the Recan Center for Integrative Medical Sciences and Keio University in Japan conducted a study involving 7 perennials over the age of 110, of whom tens of thousands of cells collected, to study the difference between them and those from people between the ages of 50 and 89.

By studying these cells, scientists found that the "cause" of the long life of the old people was not due to their lifestyle as was commonly believed, but to the nature of their immune system, which is different from what is found in human bodies at younger ages.

The difference lies in white blood cells, specifically what is known as T cells.

In the elderly, scientists have found that T cells directly attack viruses and cancer cells, while not attacking them in the normal person, Science Daily reported.

The number of cells CD4 T, a type of immune cell, is higher in the old people than in younger people, and the "task", these cells also vary.

For younger people, they play an "auxiliary" role, i.e. they help other white cells fight infections, infections, and cells that may develop cancer.

For the elderly, they attack viruses and diseases.

This is in addition to studies conducted in the past, which have noted that older people appear to be more adaptable to heart disease, cancer, and others.

"People who have lived exceptionally long lives tend to spend their entire lives in good health," said Dr. Kosuke Hashimoto, lead author of the study. This means that their immune system is active to protect against infections and tumors."

There are great examples of characters who have long lived despite their unhealthy habits, such as smoking and drinking alcohol.

Last year, an American man named Overton, a World War II veteran, died at the age of 112, after his long life he used daily doses of ice cream, cigars, and whiskey.

In 1997, Frenchwoman Jean-Calment died at the age of 122 with a sound medical record, making her officially the oldest person to live, but she remained a sinister smoker for most of her life, claiming that olive oil, wine, smoking, and chocolate had kept her alive for a long time.
