I see a wiser person than when I was younger: having babies and passing 30 were the turning points. What women in their 40s - I am 39 - lack in gorgeousness they make up for in wisdom. I love ageing despite the drawbacks - thinner drier skin.
I remember when humor was gentle pokes. I used to call it 'arm around the shoulder' humor. Now they go for the jugular and they take no prisoners. It's mean mean stuff.
