What happens when you sleep

Last night, I was watching an Australian Open match between Roger Federer and Tomas Berdych. Berdych won the first set 6-4 and then won the second set tie-break 7-6(4) . It was around 10pm by that time and I was tired from the day of PCATing so I went to bed, expecting to wake up the next morning and read about how Federer was upset in the 4th round. Isn't it interesting that I stopped watching the game right at the worst possible moment (I am a Federer fan, so it was the worst possible moment in my opinion). Apparently, right after I went to bed, Federer somehow pulled himself from the brink of elimination and won the match in 5 sets. Now if I weren't a science and statistics student, I might just get the impression that it was me going to bed that led to Federer winning the match. Even though I know it probably won't have any effect, I'm probably going to bed a little earlier from now until the end of the Australian open. I think this situation is similar to that of global warming. Sure, it is difficult to determine whether the cause of global warming is due to human intervention, but would it really do any harm if more people recycled, conserved energy and started driving hybrid cars? Worst case scenario: nothing changes but at least nothing gets worse.
