Absolutely right. A man can be in as good shape as possible, have a bright future ahead of him, be intelligent, wordly, warm and even a little bit unpredictable...but if he loses his hair over the years then forget it.
The reason that people say that "men age better than women" is because people only look at men who keep their hair e.g. Clooney, any average 30 year old with a NW1 or NW2. It just goes to show that NW6 men aren't considered valid 'men' by society. They're in a separate category altogether.
