I wonder how this correlates to Prostate Cancer. From what I heard, high testosterone can be one of the causes of Prostate Cancer. But that is over a long time.

So if levels are falling, is prostate cancer lowering a little bit ? But that will be hard to determine due to the advancement of Medical Treatment over the past 50 years.

Plastic Bottles also replaced glass starting in the early 70s too. I remember reading some type of plastic can leak estrogen into the food. So seems a lot of things happened of the past 50/60 years that will impact ones health negatively.
