I watch Doctor Who.
True blue Whovian here.
It's about this Time Lord who travels through time with a companion. He cheats death by regenerating. Same guy, different face. That's how the show's been going on for 50 years. And the next Christmas special will see his last regeneration.
As far as I understand the show, he becomes younger and younger each time, right? If so, then he has at least a few more seasons, where they can go from his young age to his old age, right? Or does he suffer from an accelerated aging process?
Don't watch the show, but was always mildly interested in its concept.
