Interesting essay. It's rare to find married men, or men in any kind of intimate relationship for that matter, being as reflective about their lives as you have been, so credit to you for that.
My own views on evolution (I don't look at it along gender lines) are quite far removed from yours, but that's probably because our lives are very different, but I enjoyed reading what you had written.
I'll seek out one or two of the songs you've listed, as they are all new ones on me.

Nice, I love (and can definitely relate to!) that Ron Sexsmith song!
