There's no evidence that japan has lower testosterone than an average country. The only study I could find suggested it had a higher average than the US.
That supports what others have commented, which is that obesity is likely the main culprit, at least in terms of low testosterone. The US has a much worse obesity problem than Japan does.
I don't see why, there's a physiological basis for it. It's well known that fat cells have higher level of aromatase which converts testosterone to estradiol.
As others have said: sedentary lives in front of screens, declining nutrition and rising obesity are all culprits. Western media loves to gawk at Japan from a cultural perspective but I would be careful about drawing social parallels there. It's easy to cherry-pick social trends to confirm bias one way or another. But the physical and material conditions people live in are very tangible and demonstrably unhealthy.
> Men are made to be dumb, reckless and horny, the moment they become cerebral, emotional and scared that's the signal that society is on the brink of collapse.
This statement is wholly unsupported by history or science.
Those "experiments" have long since been recognized as broken and invalid. The mice were severely overcrowded, because Calhoun didn't actually understand the animals' need for spread out, large territories, and was more concerned with churning out dozens of ridiculous mouse-panopticons.
Mice have biological processes that are sometimes analogous to humans, making them useful for some forms of experimentation. Their social behavior is anything but human-like.
That is because when you look closely at factors that led to those wars, you find people reacting on self interest in situations where going to war is has high chance of being beneficial to them.
It is easy to create slogans and such. But real history when you look at it is not as simple as dumb guys being dumb.
If past performance is not an indicator of future outcomes than why did you reference history(the past) in your last point to reinforce what you think will be happening in our future?
