    You can usually just ignore it, and most of the time screwing with memory will do
nothing or make your program crash.  I've talked to many programmers and I've never
actually hear of a recent even of hardware breakage, so you can put it out of your mind
unless you are working on an old machine or on a VERY CRITICAL system.  All-in-all, it
is practically impossible to accidentally hurt hardware, but my point was to show you
that it was still possible under certain very unlikely conditions.  (odds around 1 in
2^10000)
