Laptop heat- shortened life??

Hello all,
I have a Toshiba Satellite laptop with a 2.0GHz Mobile Pentium 4-M processor. The exact model is the A10 5WM (Made by Toshiba Canada- http://www.shoptoshiba.ca/webapp/c [...] nbr=2071). While running a game recently, I realized that it was quite hot, I checked my temperature monitor, and saw that the processor had heated up to 71 degrees celsius (and seemed to be stable there). I checked and found out that the game was, for some reason, using 100% of the processor all of the time, even on the plain menu screen with nothing happening. I'm (relativly) certain that 71 degrees will not hurt the computer directly, but I was wondering- will high heat shorten the over all computer life? Will it cause eventual damage to anything in anyway? Cause the processor to prematurly fail? And is 71 degrees C an unreasonable temperature? Also, are there any easy things I can do to lower heat?
Sorry to rattle off so many questions at once, but any information would be appreciated, as this computer has to last me a few years.

Ok, thanks everyone, I won't worry about it then. I just got a little jumpy when my chip that usually runs around 50-60 C started to hit above 70. Thanks for the solid advice. Im not too worried about the hard drive temp. It stays constant in the mid 40's (celsius) even under heavy use. (That IS an okay temperature for a HDD right?)
