I would disagree, because bald men are often wise - cf. Jean Luc Picard?
Frieds, could we add a rule to include statements of "I hypothesize" as well as "I think" and "I believe"?
I hypothesize that in some ancient semi-intelligent society, they thought that hair came from seeds sown in the scalp while the baby is in the womb.
the Romans thought that blackheads were little worms, I think, so hair-seeds? not so far fetched? and when you go bald, your ground is exhausted?
