Too Many Children Will Shorten Your Life

Many children have a lot of luck is a slogan that is now modern families are becoming obsolete given the increasingly high cost of living and education. According to scientists, many children also can mean shortened lifespan.

Scientists from the University of Gothenberg using modern genetic techniques to study the aging process in bernacle goose species has the longest. The research team says that there is a direct correlation between the reproductive life expectancy.

The key to understanding the link between these two things are telomeres, the protective caps at the ends of chromosomes. Long believed to be short telomeres exhibit's lifespan.

Geese were used in this study ranged from young geese to the elderly, the age of 22. Each goose measured telomere her in two situations with a gap of two years.

At the end of the study the researchers found that bernacle geese (Branta leucopsis) had longer telomeres than other bird species. It is believed to be due goose have fewer children so that they have plenty of time to maintain healthy body functions.

"There is a clear correlation between the reproduction and the age of the animal world. Example an elephant has a long life but little offspring. While short-lived mice and produce many children per women," said Angela Pauliny, one of the researchers.

Also note also there is a difference between telomere growth by gender. In men, they developed the telomeres in a period of time, while in the female cycle faster.
