Another forum I'm a member of always has a mahoosive thread on this every year.
I'm currently unshaven...er, for quite some time (2 years?) but run the clippers over a couple of times a fortnight.
Forgot again this year too. Never got around to being clean shaven then growing the top lip fuzz... takes longer than a month to look half decent anyways lol, but then I'm not one of these hairy neanderthal types with sandpaper 5 o'clock shadow by breakfast time
