Sport is great. Sport is good. From childhood we were taught this simple truth. And although the evolutionary advantages of athletes are obvious, and the duration of their lives uniquely exceeds the average (although not without exception), what is involved more: the brain or muscles? How do intellectual sports like chess affect the quality of a healthy life? The science fiction writer Isaak Azimov once wrote: "In life, unlike chess, the game continues after the shah and mat."
The scientists conducted a study of regional survival of international grandmasters (MG) against the background of the general population and compared the index of relative survival of MG with Olympic medalists (OM). The results of the study were published in PLOS.
The study covered 1208 MG and 15,157 OM from 28 countries, information on which was extracted from publicly available data sources. The Kaplan-Meier method was used to assess the survival of the MG, and the Cox proportional hazards model was used to adjust the survival rates for the regions. The relative survival rate was calculated by comparing each MH or MI for the years of risk, the age of risk and sex with the country's life-cycle table presented by the individual.
It turned out that the survival rate of MG at 30 and 60 years from the time the title was achieved was 87% and 15%, respectively. The expected life expectancy of MG at the age of 30 was 53.6 years, which is significantly higher than the average life expectancy of the general population. The analysis showed that both MG and OM have a significant survival advantage over the general population, and at the age of 30 there was no statistically significant difference in the expected survival of MG and OM.
What does it mean? This means that elite chess players, grandmasters, live longer than average and demonstrate survival at the level of the best representatives of physical sports.
