According to experts, a person's age can also be estimated by looking at his nails.

Everyone in mortal life wants to know how long he will live. Recently, in a research, Dr. David Sinclair has given shocking information about human age.

Dr. Sinclair, a famous physician of Harvard Medical School, explained how by looking at a person's nails, his physical condition can be estimated and his probable age can be estimated.

A special research was done in 1979

In 1979, scientists took measurements of the nails of hundreds of people over several years. After this it was found that after the age of 30 the growth rate of nails starts decreasing by 0.5% per week.

What does the research say?

In an interview given to Daily Mail, Dr. David Sinclair said that if nails grow rapidly and have to be cut frequently, it means that the 'biological age' of the essential organs inside the body is gradually increasing.

This means that your age is increasing over time, but your vital organs such as heart, kidney, liver, skin and lung cells are not aging as fast. If nails are growing fast, it also means that your vitality is high. If you have to clip your nails frequently, it may indicate that you may live a long life.

Dr. David Sinclair says he pays special attention to nail growth. He said, "Whenever I have to cut my nails, I count the last time I cut them."

Relationship between aging and nails

According to science, as we age, blood circulation slows down. This means that less nutrients needed for nail growth reach the final parts of the body. Additionally, diet can also be an important factor, as people who lack nutrition have slower nail growth.

In addition, hormonal levels also have an impact. Nails can grow rapidly during adolescence and pregnancy.

Other health problems related to nails

Nails also indicate many diseases. Not only age, but also many health problems are reflected in the nails. If there are many lines on the nails, then be alert.

It is normal for the elderly to have lines on their nails, but different types of marks or lines on the nails of youngsters can be a sign of a problem. Signs of deficiency of zinc, vitamin A, calcium and iron in the body can also be found through nails.
