The Edge Annual Question of 2008 is: What have you changed your mind about? Why? Lots of fascinating responses from interesting people, mostly science-related. My response would be a bit more personal: I've changed my mind about wanting to be a dad. I never thought much about having kids and didn't see the point of it, fulfillment-wise. I'm sure my life without Ollie would have been nice but nothing compared to this. (Happy 6 mo. bday, little guy!)
