The last time I took mine off was for RAF Aircrew Selection at Biggin Hill when I was 16 - I kept the 'tashe though!
My wife (now a bus pass holder) has never seen my chin.
I am scared to even think of what my chin looks like under the hair - though by feel I can tell that it still has a Kirk Douglas Dimple!

Beards are eco friendly and also allow you 15 mins more time in bed of a morning!
