I can't make assumptions as to whether you or the gp have kids, but I didn't have my first until 37 and the second last year at 41. For me personally, having kids was the single most trans formative experience of my life with regards to how I have to examine my life and the world around me. Nothing before that came anywhere close, perhaps if I had lost a parent/sibling when I was younger or had enlisted after 9/11 I could say something else was in the same league, but as it stands, kids in my late 30s is it for me :)
