Does the physiologic/natural effect of testosterone make you curious about the link between the physical and spiritual realm? I am all about promoting self control but it is interesting that sexual immorality (I know there have been a lot of debates on that over the years here) is clearly the balancing point/tip toe of cost-benefit over human history regarding testosterone. Without testosterone basically none of us would be here from a civilizational point of view and children producing one. God knows women are fairly ambivalent in comparison regarding sexuality.Yeah, my happy zone is around 750. My doctor wanted me to try to 140 because he said most guys tend to like the 900 range, but I started turning back into my old self a bit too much for my liking. My natural level in my twenties was probably above 1000.
