My thoughts on beards.
1. My wife finds it attractive. That's all the reason I need. I do not like women with hairy legs or hairy arm pits. My wife grooms herself for my taste why shouldn't I so how reciprocity.
2. My children love my beard. Since they were little they would rub it and run their fingers through it for comfort.
3. I love my beard. It throws people off when they see a big dude in a nice suit with a nerdy bow tie. People never forget me.
