A U.S. study has found that middle-aged women (of age group 45-54) are twice more likely to suffer from heart stroke than the men of the same age group.

Lead researcher Mark Kaplan said the study compared data between non-veterans and those who served the military between 1917 and 1994. Surprisingly, the researchers found that white men, and those with better education and older men, have a higher chances of killing themselves, as well as those with physical or emotional disability
