Keep an open mind MW. You know DB 101, a beginners mind.
I thought the same thing before I read the book, then I realized how much of what was written still applied to me. You know not every person that goes through menopause (male or female) is depressed. We are still affected by changing hormones even if we do not go off the deep end and have a MLC. But by understanding this stuff a little more then you are able to better relate to what the women are going through.
I can give you a short story 18 months ago when I was reading that book I strained a muscle in my ankle. Went to the doctor who suggested rehab for my ankle and said. Oh that is a very common injury for middle aged guys. I laughed and show him the book I was reading. He laughed and told me I was nuts. But the bottom line is injuries like this are described in the book. What you find out is that at midlife the weakest parts of your system are attacked by your own body. So if you had an injury earlier in life it is worse at midlife.
Look around you, how many people your age are getting cancer or some other illness out of the blue. I am a little older than you and maybe it hasn't hit you yet but trust me it will!
