[time-nuts] Determining Time-Nut infection severity.

As usual, it seems I was incorrect. At least in the US legal system,
clinical death is considered to be the cessation of blood flow due to
heart failure and similar due to breathing having stopped. This,
apparently, means one can be brain dead but still considered to be
alive. Thinking about it now, I'm sure I have met some people who fit
that description :)

It's also interesting how long one can be clinically dead but still be
revived, depending upon the circumstances and the treatment one
receives at the time of medical intervention. To this extent,
modification of the "TOD hat" should in fact timestamp the cessation
of the heartbeat and then trigger peltier devices to cool the brain
area in an attempt to prolong the resuscitation window. Perhaps one of
the propeller hats could be retrofitted with a motor which engages at
the time of clinical death and thence cools the brain area to effect
this process as well. Logically though, complications may occur in
determining the time of death if one is subjected to multiple
resuscitations eventually culminating in a final determination of
legal death at some period after. Apparently the medical profession
has a saying that "you ain’t dead until your warm and dead", as one
may be successfully resuscitated, but damage caused by Ischemia can
result irreversible death some time later.

To this end, I think I'll have the headstone engraved with "Died: 21st
century'ish (approx date can be determined by carbon dating)". Also, I
will donate the fertile earth from the 6' hole of my internment to the
worthy cause of growing food for the hungry and back-fill the hole
with all the expensive stuff I have accumulated during my life. To
this end, future archaeologists may be able to determine that I had
some interest in knowing the precise time and frequency. I'm sure they
will chuckle as they look down at their $1 gas-station wrist-watches
which are kept in time via an embedded oscillator disciplined by
sub-atomic strings, being accurate to 1E-99, and wonder what the
dickens all the fuss was about.

As usual, please apply a liberal quantity of :) to my posts.
