There are lots of "old wives tales" and legends that used to be believed. One of them is that baldness in men is caused by masturbation. Was that true? Perhaps sometimes?
Yeah, "sometimes" -- the same way a broken clock is right twice a day: by accident.
I dare you to bring up that theory to Fr. Scott Gardner, SSPX who was bald by his 20's. His English classmate Fr. Gary Holden had a large natural tonsure as well.
Sodomites should all look like trolls, by this logic. Certainly they should all be bald. Wouldn't this work for women as well as men? Sorry, but there are WAY TOO FEW bald women for this to be true.
Bill Clinton has all his hair, for crying out loud! Do you honestly believe Bill Clinton is above-average in his chastity? ROFLMAO!
I'm pretty sure Hugh Hefner of Playboy infamy had all his hair as well. And I'm sure I could come up with hundreds of other such examples. Just look at Hollywood! Do you think any of them practice chastity? (either perfect chastity for the single, or chastity within marriage for the married)
And apparently (according to this old wives' tale) some nations are significantly more prone to this vice, since
I mean solitary sin -- predisposes certain ethnicities to going bald. And other races/ethnic groups almost always keep their hair until death. Going grey is the same situation: Slavs and Germans, for example, keep their natural hair color well into their 70's and beyond. Other ethnicities, like the Irish/English, often go grey in their 20's. It's 100% genetics. It has zero to do with lifestyle.
I'm not normally one to pick up the pom poms for science, but Old Wives Tales like this is one of those few rare times the "olden days" come out smelling like dung, and hooray for science!
Catholics aren't supposed to be against true science, by the way. Science is supposed to be about truths of the natural order.
