Tip o' the hat to Dave.
Researchers at the University of Washington School of Medicine studied 2,000 men aged between 40 and 47.
They were able to link high levels of the male hormone testosterone in those who lose their hair earlier with a lower risk of tumours.
The findings are published in the journal Cancer Epidemiology.
Half of the men in this study had suffered prostate cancer.
Researchers compared the rate of tumours in those who said their hair had thinned by the age of 30 with those who did not suffer hair loss.
Men who had started to develop bald spots on the top of their heads as well as receding hairlines had a 29% to 45% reduction in the risk of prostate cancer.
As the Bible tells us, making fun of bald men is a very bad idea...
From there Elisha went up to Bethel. While he was on the way, some small boys came out of the city and jeered at him. "Go up, baldhead," they shouted, "go up, baldhead!" The prophet turned and saw them, and he cursed them in the name of the LORD. Then two she-bears came out of the woods and tore forty-two of the children to pieces. - 2 Kings 2: 23-24
