The Crazy Thing Marriage Does to a Man's Testosterone with Dr. John Gray

from Age Defiantly with Mark Young

When the book Men Are from Mars, Women Are from Venus was published in 1992, nobody could have predicted it would sell tens of millions of copies in more than 50 languages. Most people picked it up looking for communication advice. Its author, Dr. John Gray, has spent the decades since arriving at a different conclusion. The reason men and women struggle to understand each other runs deeper than how they talk. It runs through their hormones. At 74, John is living proof of his own thesis. His testosterone is higher now than it was in his 20s. He produces almost no cortisol. He's been married twice, raised children, and built a 40-year career as a relationship counselor and author of more than 20 books. The science, he says, has finally caught up with everything he was already teaching.
