Secret to women's longevity is in the genes: Having two X chromosomes promotes survival, study suggests
When it comes to the secret of long life, the answer may be in your genes. Women live longer than men, a study suggests, because they are lucky enough to have two X chromosomes.
It is said that women outlive men because they have stronger immune systems
Female animals live longer and scientists believe chromosomes are significant

Females have XX chromosomes and males have XY. But the Y chromosome does little except create men’s masculine features, like facial hair, while the X contains many of the genes related to the brain and survival.
When scientists engineered biologically male mice to have two X chromosomes like a female, they lived longer.
Dr Dena Dubal, senior study author, from the University of California, San Francisco, said: ‘It didn’t matter if they had ovaries or testes.
'As long as they had XX, they escaped early death during ageing.’
