Just yesterday I was talking with a guy friend of mine and we some how got on the topic of age and looks.  We ended up discussing what he thinks is the disparity between how men are expected to look as they age and how women are expected to look.  According to him, men get to keep it natural - turn gray gracefully, put on a little weight around the middle, lose a little hair and it's just expected and ok.  Men are considered wiser when they are gray where as women are just considered older.  Is this fair?  Why…
