Worldwide, men have a life expectancy of 64.52 years, as compared to a life expectancy of 68.76 years for women.
The most common cause of death for men in the U.S. is heart disease (the same as for women), and the average age of a first heart attack for men is just 66 years.
In the U.S., men have higher death rates for all of the 15 leading causes of death (with the exception of Alzheimer’s disease) and die more than five years younger than women.
The brains of adult men are about 10% larger in total size than the brains of women. Because men generally have a larger stature and more muscle mass than women, their brains require more neurons to control the body.
Scientists have discovered than men’s and women’s brains actually function somewhat differently. When focused on a task, men tend to use only one side of their brain at a time, devoting all of their attention and concentration to the task at hand. Women, on the other hand, tend to use both sides of the brain at the same time, making them more adept at “multi-tasking.”
Boys typically experience puberty between the ages of 12 and 14, a time in which the voice changes to its lower timbre, growth spurts occur, and the secondary sex characteristics begin to develop. Puberty for boys generally occurs later than in girls of the same age group.
The “Adam’s apple,” or laryngeal prominence in the neck, is a feature primarily unique to adult men and is a result of the growth of the larynx during puberty. The term is derived from the Biblical account of Adam eating the forbidden fruit in the Garden of Eden.
