My son got his first kilt for his first birthday. He's been growing a beard since he was four. He's now seven. Let's just say he has slow-growing facial hair that's nearly invisible. For him, it's all about convenience. He doesn't shave, because it saves a lot of time and blood. I think he started on the beard because he saw a clip of Her Majesty Mrs Brown and thought Billy Connolly looked sharp with the beard and kilt.
