I would say that is as good of an explanation as any, from science. Personally, I felt like God was there saying “Well done my good and faithful servant”.
I do not think Runners feel the same thing... I have been quite a runner as well. It goes far beyond endorphins. It would be helpful if other women shared their experience, but a lot of them have been robbed of it, very sad. Somehow the cursed pain of childbirth is lifted for a few moments and God is definitely there. This was more prominent in my first birth. If I could capture it and keep it.. wow. I cannot expect a scientist or a man to understand. Sorry, guys.
Thanks!
