 Ok Sven. You are convinced about your idea, but I am still skeptical.
 In order to persuade me, I need a proof. Please perform this simple
 experiment, then report the result. The experiment is as follows.
 Have a nice and long trip with your car, then come back home, and
 switch the engine off ensuring that the cooling fan is not spinning.
 Let us know if your car starts again the next day.

 If you prefer, you can perform the similar experiment with your brand new
 PowerBook 500Mhz. Just run an intensive floating point application
 for a long time, then shutdown. Keep doing it every day, for a week
 or so. Let us know it your jewel works fine at the end of it.

 Friendly,

 Sergio
