When I was an active JW I tried the beard thing and at the time I grew a goatee that was well groomed ,I soon got the attention of the P,O, as they were called at that time.
And I was pressured to give it up .Many years later I tried it again and got a slap on my wrist so to speak and had to give it away again.
I`ve been out since 1993 and haven`t been without a well groomed beard since then .
