Smart people usually live longer than normal ones?

Scientists at the University of Edinburgh have shown that genes related to thought ability are also related to health.

For the first time to date, scientists have shown that intelligence and good health are interrelated, so people with smart brains almost never get sick or die early.

The reason is purely in their genes. An international team led by the University of Edinburgh has just discovered that genetic variants that make people intelligent are also protecting them from illness.

The best people in such things as memory, reasoning, or reaction time tests will almost certainly not have genes that lead to problems like high blood pressure, development of symptoms like Alzheimer's, diabetes, or overall bad heathy. The research shows that these people will also have the higher height and a bigger brain than normal people. The things that intelligence can increase the likelihood of appearing are schizophrenia, autism, and bipolar disorder.

Dr Saskia Hagenaar of the University of Edinburgh said the study also supported previous theories that suggested people with good health often had a higher level of intelligence.

Dr. Stuart Ritchie, of the University of Edinburgh of Edinburgh also added: "This study tests whether genes related to mental ability or education are genes involved in disorders. We see a lot of coincidence: for example, genes related to height are related to having college or university education.”

To explain the links among genetic variants, health and intelligence, the researchers analyzed data on more than 100,000 people at the age of 40-73. After comparing each person's mental test with their genome, the researchers found that some of the traits associated with the disease and ability to think had the same genetic effects. Super-level genes will also involve the taller height and a larger brain.

Previously, the scientists thought that new socio-economic factors were the main cause for the link between poorer education and poor health. But this new study suggests that genetics plays a very big role. So, the smart people with poor conditions will have a better chance of living well than those who are less intelligent.

Professor Ian Deary, director of CCACE at the University of Edinburgh, who led the research, said: "In addition to showing cognitive ability and some mental status. The study also found that cognitive abilities also shared genetic influences on brain size, body shape, and academic performance.”

The researchers hope this study will help us understand the connections between cognitive ability and health. However, the researchers also point out that many other factors outside of the environment will also affect over time. The study was published in the Journal of Molecular Science.
