Sports are great. Sport is good. Since childhood we have been telling us this simple truth. Although the evolutionary advantages of athletes is obvious, and their life expectancy exceeds the average by far (although not without exceptions) that the more involved the brain or muscles? As an intellectual sports like chess impact on quality of healthy life? Science fiction writer Isaac Asimov once wrote: "In life, unlike chess, the game continues after checkmate".
Researchers conducted a study of regional survival international grandmasters (MG) on the background of the General population and compared the index of relative survival MG with Olympic medals (OM). The results of the study were published in PLOS one.
The study was affected by 1208 MG 15157 OHMS from 28 countries for which information has been extracted from publicly available data sources. To assess the survival rate of MG was used the method of Kaplan-Meier, and for the adjustment of survival of the regions used the Cox proportional hazards models. The ratio of the relative survival rates were calculated by matching each MG or Ω years of risk, risk age and sex table life cycle countries represented by the individual.
It Turned out that the survival of MG 30 and 60 years after achieving the title was 87% and 15%, respectively. The life expectancy of MG at the age of 30 years was 53.6 years, which is much higher than the weighted average life expectancy of the General population. The analysis showed that both MG and OM have a significant advantage in survival to the General population, and at the age of 30 years was not a statistically significant difference in the expected survival of MG and OM.
What does that mean? This means that the elite chess players, grandmasters, live longer than average and demonstrate survival at the level of the best representatives of the physical sports.
a Group of Australian and British scientists came to the conclusion that the love of junk food and exclusion from the diet of fruit can lead to difficulties with conception in women of reproductive age.
it was thought that hormonal contraceptives and ovulation influence women's preferences with regards to men.
the Main problem of modern cryonics (the science of freezing living tissue) is the difficulty in unfreezing these tissues so that ice crystals don't hurt a living material.
