Because we take a circular trip around our star system we interrept this look for marking our time.  One trip one year.  Because we make a revolution around the marking is 24 hours.  We base our seconds based on our movement around our closet heaven.  We gravitate and come together but more exist both space and time both larger and both much smaller.  We may not need to seek longevity we may not be taking advantage of an imortality by moving too quickly and need to slow it down to see the infinity which exist between seconds one and two.
