How common is this level of hirsutism?

I recently saw a guy (just out walking on the street) whose beard was so “high” that it basically merged with his eyebrows. Actually, to be accurate, I should say eyebrow, singular – he had a massively thick unibrow that looked like it got bigger towards the middle.

(I did not want to stare, so the 'bigger towards the middle" eyebrow might have been a trick of light and shadow, but I do not think so. And the beard definitely did merge with the eyebrow.)

Now, the man did not look homeless or destitute; he was nicely dressed.
In its own way, his look was kind of interesting! Different, but certainly not ugly!

This odd encounter got me to thinking – men generally trim their beards. If left completely unchecked, would many men’s beards actually get high enough to merge with their eyebrow(s)?

As always, any information would be appreciated! Thanks!
