WOMEN LIVE LONGER THAN MEN; WHY?
This is a well-known fact that women holds longer telomere length than men worldwide. 
Why do women live longer than men?
This also implies that the environment, lifestyles, and other factors that may play a role in a person’s longevity may be trumped by biology. The reasons women live longer than men have been elusive but have nevertheless been well investigated and many explanations have been pushed forward. 
A large group of scientists investigates why women live longer than men.
A recent scientific article from a large group of investigators spanning from John Hopkins University, UCLA, University of Pittsburgh, and the University of Michigan, have investigated in a combination approach both biological and behavioral reasons for why women live longer than men (Biodemography and Social Biology, Vol. 60, Issue 2, 2014). In this study, the researchers took blood samples from 851 volunteers composed of men and women aged 45 to 84 years.
What did the researchers find out about why women live longer than men?
The researchers found that women had longer telomeres than men. They speculated that the differences in telomere length might be why women live longer than men. Interestingly, they also observed that the telomere length difference is negligible as both genders get older. In addition, the researcher acquired information on the volunteer’s behavior, hoping to find clues on the effects of lifestyle and the environment’s influence on telomere length. On this note, the researchers observed that gender differences in smoking and consuming processed meat affected telomere length. Whereas estradiol, testosterone, oxidative stress, and body mass index were not affected by gender differences. The authors concluded that long-term studies were needed to confirm the gender differences. 
Meanwhile, we recommend that all guys take care of their telomeres by taking some extra TA-65!
