Why more men, not women, are likely to die in their youth

I recently found myself in Lang'ata public cemetery. I found out that more than 70 per cent of those buried there were young people, aged below 35. Of this, more than 55 per cent were young men. Why are our youthful men dying so young? Popular culture may paint men as the stronger sex, but from the moment a boy is born, his life is more likely to be cut short than his sister's. Across national and cultural boundaries, men die an average of seven years earlier than women.
