Well, here is his underlying assumptions (that he's not really stating):
1. Earth is a nasty, toxic place.
2. Most of it is caused by males, esp. younger high-testosterone males.
3. Virtually all torture, wars and violence is caused by middle-aged and younger males.
And here is the big assumption:
4. How can we re-engineer humans to eliminate #1-#3?
This may seem silly, but trust me it will be a huge issue in the next 100-200 years. We'll have to decide if we are going to re-engineer our kids and/or re-engineer societies. Oy vay!
I don't like his solution and wish there was a better way. I can't really argue against #1 - #3, but I don't want to be turned into Barney or Fozzy Bear to try to solve the world's problems.
And that leads to some really big questions:
Isn't there a high testosterone way to undo #1-#3?
Are there spiritual solutions that can help?
Well, I'm not going to go there.
NOTE: He says that the higher the testosterone, the lower the oxytocin. But he says that using social media can increase oxytocin, so perhaps there are solutions to have high T and decent oxytocin?
