Heroes are important. Heroes tell us who we want to be but when they made this particular hero they didn’t give him a gun, they gave him a screwdriver to fix things. They didn’t give him a tank or a warship or an X-Wing, they gave him a call box from which you can call for help and they didn’t give him a superpower or a heat-ray, they gave him an extra heart. And that’s extraordinary. There will never come a time when we don’t need a hero like the doctor.
