The beard diverts attention from the rest of his face and from the fact that he's getting really old, and it makes you almost forget that he'll be needing a walker by the time Ep VIII gets released ;)
Always with the walker jokes. Just because you're old doesn't automatically make you a weak feeble push over. Look at Bill Shatner:

The man is 83 years old and still going strong. Harrison is a whole 12 years younger than this man and you're already ready to relegate Han Solo to the old folks home?
