Bad To Frequently Reboot Computer?

I own a 15 inch mid-2010 macbook pro and have Windows installed via bootcamp. Because of this, I often shut down and reboot the computer into the other partition. I would say I switch between Windows and Mac OS X about six times a day.

Since I reboot often, I was just wondering if doing this does any damage to the hard drive or other hardware.

Thanks

 

Thank you; just making sure
