P2P vs electronic medical records are not really that related. Although I agree the government has not always kept records safe, neither has private industry. I thought the main problem that electronic medical records was meant to fix was making sure information could get from one doc or insurance company correctly and securely. At least several years ago when I looked at this, the insurance company had an incentive to have things mis-tagged so they don't have to pay. Therefore they were reluctant to standardize systems.

Since you seem to question all of this as common wisdom instead of logic. 1- There are many items that are affected by the cooling and heating of powercycling. They include light bulbs, monitors and hard disks. You can sometimes find numbers for Mean Power Cycles between failures as well as MTBF. 2- Reducing the MTBF usually means you are increasing the failure rate some before you reach the mean time. 3- This is hard to know for sure, but consider that replacing a ram stick is cheap only after you have determined that is what is causing random crashes and wasting a good bit of user time. The lost productivity costs and diagnostic time may easily swamp the power savings.
