Some of that report is the result of a misunderstanding:

   my Load_Cycle_Count is now at 718,694.  this is very bad because the
   average Load_Cycle_count before failure for most hard disks is 600,000.

This is simply not true.  Most laptop drives have a specification that
says that it should survive approximately half a million
spin-up/spin-down.  But Load_Cycle_Count is not spin-up/spin-down (which
is tracked by Start_Stop_Count instead).  Most drives specs don't say
anything about the expected number of "load_cycle" that the drive is
expected to survive.  This high number of load_cycle is because the
drive aggressively moves (unloads) the head away from the disk after
a very short time of idleness.  It does this not so much to save power
as to avoid crashing the head against the disk in case of a shock.
I.e. this number is high so as to avoid data loss.

Other drives only unload the heads when the disk spins up/down, so on
some drives Start_Stop_Count=Load_Cycle_Count.  Yet others don't even
bother to report Load_Cycle_Count.

I wouldn't worry about it,
