I still have lots of hair, albeit probably a bit fine nowadays.  I hate long grey hair so I keep mine at Number 2 length.  A good compromise I think.

I keep my sack shaved and apply powder.

All the better for slipping down the chimney, but let’s keep that as our little secret, eh, Santa? Before the boys on Crimewatch 5 get too curious....

Depends on how long your Number Twos are.

If you’re going to use the length of your Number Twos as evidence of innocence, you might want to post a sample to a presiding magistrate with a reference to the alleged incident in advance of it’s presentation to the court.

If you need hair on your head to attract the women you've already lost the race.

 

Getting an inexpensive electric 'haircut' clipper with multiple settings will do the job just fine.  3mm, 6mm, 9mm, and 12mm seem to be the most common settings. Personally, I like the 3mm for my head and the 12mm for my beard. Haven't been to a barber in about 25 years.
