Today, there is nothing extraordinary in the fact that a person has reached the age of a century, because there are thousands of such individuals in the world, and their number is constantly increasing over the years.
A group of Italian scientists from two Roman universities decided to consider how long human life can be. Every year there are more and more long-lived people in the world, and the total life expectancy is increasing rapidly. Many scientists are working to figure out how to prolong human life as much as possible. The results of their research were published in the journal Science.
Scientists have determined that it is impossible to accurately establish the limits of the duration of human life, but there is a "guarantee period" - a conditional period for which internal resources are sufficient. This term was determined - it is 105 years.
In addition, scientists have established that the most important thing is to cross the bar at the age of 80. Until this age, the risk of death is constantly increasing, and after it it begins to decrease and stabilize. Moreover, those who live to age 105 are 10% more likely to survive the next year.
In addition, after 80 years, the risk of developing cancer decreases. Cancer researchers have already noticed this feature. The peak incidence is observed at the age of 60-75 years, and then the risk decreases. This is probably related to the effect of aging processes on cancer cells.
