How can a person check if he will live to be 80 years old?
A person can test whether he will live to be 80 years old.
This can be done using a test invented by Japanese gerontologists.
How to do a longevity test
This test was invented by Japanese gerontologists as a result of many years of research.
Its essence was to measure the walking speed of people aged 60 to 80 years.
The study began in 1997. Measurements taken 10 years later showed that older Japanese people began to walk faster.
The walking speed of the average Japanese person has increased by 5-10% over 10 years.
In addition, the study allowed Japanese gerontologists to establish the following pattern.
If a 70-year-old person maintained a brisk walking pace (one and a half meters per second), his chances of living to 80 were high.
If the walking speed was no more than 0.5 m/s, the probability of living to the age of 80 was 15-30%.
At the same time, women had a higher chance of reaching their 80th birthday.
The study also found a steady improvement in the physical condition of people aged 60 years and over.
According to scientists, old age, understood as infirmity, is being pushed back in both women and men.
