According to my favorite Time Lord, time is a "big ball of wibbily wobbily timey wimey ...stuff." Einstein said time was relative; it depended on whether you were standing on the station platform or sitting on the moving train. The best anti-aging treatment is traveling near the speed of light.
We are fascinated by time. There is never enough. It goes so slowly. It goes too fast. It heals all things. The past is never dead. It's not even past. According to quantum mechanics, it may move in two directions. Who knows what time does in those parallel universes?
I try to live in the moment. I have no idea what that means.
