Telomeres are the protective caps on the ends of chromosomes, and are the best indicators of biological age (age phone) of people.

Scientists say that telomere length is crucial in determining the biological age : the long telomeres indicate a healthy aging , short ones indicate some form of irreparable harm . Several studies suggest that telomere shortening is accelerated by stress, but until now no study has examined the effects of social isolation on telomere shortening.

To test whether social isolation accelerates telomere shortening Denise Aydinonat , a doctoral student at the Vienna Vetmeduni conducted a study using DNA samples collected from African gray parrots during routine checks . The Greys are highly social birds , but they are often bred and kept in isolation from other parrots. Denise Aydinonat and his colleagues compared the telomere length of individual birds than in pairs in a wide range of ages ( 1-45 years).

The telomeres of the older birds are shorter than in younger birds , regardless of their status . But the most important conclusion of the study was that the birds had shorter telomeres than single ones in pairs of the same age group.

Dustin Penn Konrad Lorenz Institute of Ethology at the ' Vetmeduni Vienna said: "This study is the first to examine the effects of social isolation on telomere length "

Penn and his team had already conducted experiments on mice that were the first to demonstrate that exposure to stress leads to shortening of telomeres. He points out that this new discovery suggests that both extremes of the social conditions ( excessive stress / excessive isolation ) influence the attrition of telomeres .

There is extensive scientific evidence that shows the strong correlation between the percentage of short telomeres and the risk of developing diseases associated with aging , such as cancer , cardiovascular diseases and Alzheimer's. While lifestyle habits (diet, exercise, smoking ... ) affect telomere length .
