Thanks Jasper... really enjoyed that!

Must admit to having had a bit of a lump in my throat towards the end... why has 'time' sped up so much, how much have I left and what am I going to do with it!?

Yeah - my sister cried her eyes out apparently!! But then, she is a girl

Did make me stop and think a bit though

Think I missed something, I waited about 20 minutes for it to happen and there was something about trees growing all over the place.. Or have I actually missed something?

Very clever, liked it.
