The greater the delay, the greater longevity?

A new study finds that the life span of an organism is influenced by the early growth of the body. In particular, the longer you grow, the more likely you are to live a long, long life.

The conclusion is drawn after scientists from Glasgow University (UK) study sticklebacks.

According to the Daily Mail, the team changed the growth rate of 240 sticklebacks by exposing them to cold or warm environmental conditions for a short time, making them 'go ahead ' or 'lag behind'. 'compared to the normal growth schedule.

The researchers found that sticklebacks will return to normal growth rates once their ambient temperature is adjusted back to their original levels. However, the change in development speed has affected their aging speed.

Large fish slow down about 30% longer than normal species of the same species, which have a lifespan of nearly 1,000 days. Meanwhile, the life expectancy of fast-growing fish is 15% less than normal.

Professor Neil Metcalfe, a member of the research team, stressed that the results 'are very noticeable' despite the fact that all fish in the experiment were of adult size.

'It seems that rapidly growing bodies have accumulated more cell damage than slower-growing bodies, and their lifespan is basically reduced accordingly. The findings are also likely to be true for many other species, including humans, because the way cells and organs in the body grow and age is similar in different species' , Professor Metcalfe said.

The researcher added that the scientific community has noted that in humans, rapid growth in the early stages of life is associated with a higher risk of later life diseases, such as heart disease. circuits in middle and senior stages.

Earlier attempts to test the relationship between growth rate and life expectancy by changing diets were not convincing because the results obtained could be influenced by the diet. not because of its impact on development. The Glasgow University team avoided this by keeping the sticklebacks with identical diets. All that changes is just their habitat temperature.
