I can understand how awkward it must have been for matelots to shave when bobbing up and down on the briny centuries ago, hence having a 'set' became a naval tradition, along with rum (no longer), bum (now legal...) and the cat (fortunately no longer). But for others unless it's a religious or medical thing, being a weird beard smacks of laziness.
But hey, if you want to look like a ZZ Top impersonater, trendy lefty Corbychev clone or an a***hole with dentures, that's up to you.... The impression your appearance conveys to others is something you might care to consider though.
