I've heard that once the eyebrows are shaved they can take forever (and maybe even longer-LOL) to grow back!!
Besides, take into consideration the people who are suggesting this to you... if you take their advice and "blade the brows", they may then respond to you by saying.."WTF.. OMG...You took me serious?...OMG...I was only kidding when I suggested that to ya', man.."
But if you are still contemplating as to how you would actually look to other people , I strongly suggest taking a photo of yourself, upload your pic into your computer, then go into the edit/retouch phase and "blade the brows" there. It's a much safer way to undergo the experiment. Besides, the decision to shave 'brows is very different as compared to the making the decision to go sly and should
NOT be taken lightly!! It's one of those type decisions that
regret can sink in directly behind
reality...

I have one of those "wave to as you drive by, but don't really associate with type" sly neighbors (LOL- if you can follow all that) who did just that-shaved off his eyebrows recently, and now he resembles
UNCLE FESTER from
The Addams Family!
No matter his expression, it always looks as if his eyes are bulging out of his head!!

But then again, he seems to "live outside the box" in everything he does, and he's quite happy with his new look!!
IMO, I'd say keep the brow, bro, and save the shave for ye' ol' noggin, but ultimately, you're the one who's in control and has the final decision!!
Have a good one, guys -
