Is Life a jigsaw puzzle?
It depends on your individual perception of life, or maybe more specifically, how you remember your life. Most see life as a series of moments loosely strung together by the passage of time. To take the jigsaw puzzle point of view would suggest that you see/remember parts of your life (which tend to be the interesting bits) find similarities between different ones and create an association between them. So in effect you’d be seeing your life outside of time (in which case would you be living forever? – another question for another day methinks!). So really, the number of pieces needed would depend on how many parts of your live you individually remember.
