Maybe it's just me, but my car appears to run better on a full tank of gas, and after a carwash. But I run better after a shower, too. And cell phone reception is clearer just after my account cycles and I have a brand spankin' new 5,000 minutes for another month. Also, it seems to me the time goes faster when the clock is moving downward, between 12:00 and 6:00, than it does going from 6:00 to 12:00.
