Menstruation clue to longevity in women
An American expert on longevity believes menstruation may play a part in why women are almost six times as likely to live to 100 than men.
"Dr Perls told the International Healthy Ageing and Longevity Conference in Brisbane yesterday more than 85 per cent of centenarians were women.
"Women are clearly the winners of the longevity marathon," he said.
Some scientists believe oestrogen plays a protective role in women, but Dr Perls said another theory was that menstruation, which can cause iron deficiency over a large part of a woman's life, was a factor.
