Biking and Flopping

Made it all the way in today.  Biking does take it out of me.  Feel tired now.  Tomorrow - rest.  And a big thank you to Brazil for reminding me why soccer is the sport I care least about.  Would someone from outside the US explain to me how this is tolerated?  Astounding this is so widely watched.  What is crazy is that the players seem to automatically do this - without even thinking - they just flop.
