Jakarta –
When someone’s birthday, the wish that is often said is ‘wishing you a long life’. Many people try to exercise and eat healthy for the sake of longer life.
In fact, there are several things that affect the length of a person’s life. The question is, is this also inherited from genetics?
The average life expectancy in developing countries is 80 years. The oldest human who has ever lived is 122 years old. Even so, the longevity of humans can vary, some are young or can be that old.
Science Alert as seen Monday (7/6/2021) asked aging experts, cell biologists and geneticists about whether longevity is determined by genetics.
Professor Dame Janet Thornton, an expert in anti-aging and cell biology says that genetics accounts for less than 30% of a person’s age.
“However, it’s true that longevity tends to run in families, i.e. some families have a lot of very old people,” he said.
It is difficult to determine whether the existence of a family with many very old people is due to genetics or environment, because often family members adopt the same diet and lifestyle. Learn DNA these long-lived people can actually tell us more information about this.
Furthermore, Professor Ken Parkinson, an expert on anti-aging and oncology from Queen Mary University London argues that healthy lifestyle more influential on a person’s age. The effect of lifestyle on longevity is clearly seen when we look at how the average life span has increased over hundreds of years due to increased accessibility of clean water, food and medical care.
Counter-intuitively, it was revealed that limiting calorie intake could be associated with longevity in humans. Another lifestyle factor is exercise. Even moderate exercise for 15 minutes a day has been shown to increase life expectancy by about 3 years.
In conclusion, individual longevity between humans is influenced by genetics, but this is not a major factor.
