Behavioural factors in contemporary populations
The research found that in contemporary populations, men tend to be risk-takers than women and this contributes to the sex gap in life expectancy.
“Men consume tobacco, alcohol, and psychoactive substances in greater quantities, drive less safely and eat less salubriously than women do; this results in elevated risks of cardiovascular diseases, lung cancer, liver cirrhosis, and accident fatalities,” the researchers pointed out.
But the researchers were quick to add that this cannot fully explain the sex difference in survival, as earlier explained.
