Despite having had most of the social determinants of health in their favour, men have higher mortality rates for all 15 leading causes of death and a life expectancy about seven years shorter than women's. Men's reluctance to embrace preventive strategies has also contributed to the spread of AIDS, particularly in Africa, and to an alarming rise in infections among young men, including other sexually transmitted diseases. Furthermore, there is a sustained increase in psychosocial disorders in men, including alcohol and substance abuse, mid-life crisis, depression, and domestic violence. Men's increasing aggression and autoaggression remain an unsolved health and societal problem. As you read this, over 30 wars and conflicts rage around the world, mostly created, maintained, and aggravated by men.
