What is the meaning of Life ?

Taking photographs of toddles can be like trying to catch water drop collisions ! ... 1 out of every 25 images you manage to capture gives you  perhaps one good image... this is, that one good image for today... 

Little Oliver's expression here... reassembles me (his Granddad) gazing at the clouds and wondering just what is the meaning of LIFE ? 

HAS ANYBODY REALLY WORKED THAT ONE YET ?
