In the same way that ages of trees are determined by the rings they contain within, you can consider a man’s measuring stick to be his whiskers. They come in all shapes, sizes and textures but one this is for certain; they will all end up grey. Thick or thin, long or short, cropped or unkempt, the hair that grows on a mans chin says a lot more about the time he has spent on this planet than you might realize. You cannot rush growing a beard, some men simply can’t manage it and there are thousands across the world who have turned it into an art form. Any fans of facial fuzz will have fun with A Book of Beards ($25).
