This is about Time. The mind's experience of time and our bodies' strange reactions to it.

The novelist, Kurt Vonnegut, suggested that time is not like a straight length of spaghetti, but more like a tangle where episodes occur out of chronological order and are also repeated.(Slaughter House Five)

If your children look at you and think "they've been around for  a long time", they will find out they could not have been more wrong.  For life has strobed by in summers of love and weird winters - a few beats of a humming bird's wings. Yesterday you were born, today you learnt about love and tomorrow…? (Bill Boyd)
