Now as counter intuitive as this might initially seem, try thinking of it this way. Mind enters into thought and time is lost. A subject in hypnosis loses their sense of time. What seems like 10 minutes can in fact be a matter of hours. Meditators lose their sense of time.
Children daydreaming lose their sense of time.
In the alternative, it seems that we can all make the proverbial clock stop. Watching time pass is a sure way to extend the sense of time. Take an airport delay where you are stuck on the plane waiting. Minutes seem to drag on as though they were hours. If we seek to find some simple hypothesis somewhat akin to flying a clock very fast, and this was actually done in the last century, we might hypothesize that regular meditators would live longer than non-meditators.
