The Circle of Life

The King of Spades is in town...but will this time get us any further than it ever does?
 
If life is a never ending circle (I'm happy to go with Elton and Disney on this one), then how do you know when your starting another lap all over again? And is it horrid that I don't even mind that I'm not 'learning' anything each time around.
 
I've always loved roller coasters, but it would be nice to get off the loop before nausea sets in and perhaps, just perhaps I might be too old to ride. Will it take me throwing up my popcorn and cotton candy before I realise that I need to let the rollercoaster leave without me?
