have had a full beard since I retired- about 10 years. full Duck Dynasty. Trimmed it this summer to about 1.5 inches- number 5 on my shaver. today was going to give it the last trim before letting it grow for the Buffalo winter, set it at 5 and set to face. I forgot to put the guard on it so I shaved a big spot down to the skin. so now I am sporting a mustache and some very pale skin. down side- the beard had been hiding wrinkles and age all suddenly out there for the world to see.
