I've just done it, after two weeks of the 'can't be arsed to shave' syndrome, and the response has been midly encouraging - with the other 'arf undecided as to whether I look beatifically Christ-like (unlikely, she concludes) or like a pantomine villain a la Dick Dastardly and umpteen Sherrifs of Nottingham (more likely).
My daughter is convinced that I'm merely not shaving so I look more like a "folkie" to blend in at festivals. But even she's prepared to admit that it's not as bad as it might be.
Trouble is, the bloody thing does itch, and shaving round it takes more time than just razing the whole face. The jury's still out...
