Good list but to be fair, Chick had prostate cancer which I'm sure all those wonderful DHT derivatives contributed to.
Anything is possible, but don't be too sure that DHT caused his prostate cancer. Prostate cancer statistics indicate that it is a very common disease.
"Aside from non-melanoma skin cancer,
prostate cancer is the most common cancer among men in the United States. It is also one of the leading causes of cancer death among men of all races and Hispanic origin populations. For more information, visit Cancer Among Men.
In 2011 (the most recent year numbers are available)—
209,292 men in the United States were diagnosed with prostate cancer.*†
27,970 men in the United States died from prostate cancer.*†
*Incidence counts cover about 99% of the U.S. population; death counts cover about 100% of the U.S. population. Use caution when comparing incidence and death counts."
