Jack, no no no! im saying they are likely high testosterone because in order to get rich they have been winning competitive battles along the way. It's the same thing in a different context that peak t is saying. So when monkeys win battles and become higher status in their groups they test higher for testosterone. The exact same is true in humans, and one of the ways, but not the only way, one becomes "alpha" in our society is to win competitive business battles and make a whole lot of money. But the same effect is true in athletes, that the same level athletes if you test them after a game the winners have higher testosterone than the losers. In fact the book I mentioned threw out the theory that winning streaks in sports could be caused by steadily rising testosterone of the team that keeps winning leading to a positive feedback in their level of play.
Take money out of it, the point is simply that someone who is steadily winning competitions and being successful after taking risks gets natural boosts in testosterone, whether the context is athletic, business, daredevil, women, or some other form of status. That is the simple explanation why a self-made billionaire at the point where he is on top is likely to have a higher testosterone level. It's positive feedback from success, winning, and status, and it would be the same in anyone in any context who is not hypogonadal to begin with.
