No no.
Imagine you're about .5 seconds away from death.
And at that moment you are scared half to death.
Your time to death would now be .25 seconds away.
That's such a short amount of time that you'd probably not even be aware of it, since your brain can't process all the info of your last .25 seconds alive.
So to you, you'd have been .5 seconds away from death, been scared and then immediately died. To to the individual it would seem as though they had been scared TO death, but instead were actually scared HALF TO death, and then died naturally afterwards.
Let me see how this would apply for me:
Based on current actuarial tables, I have about 59 years left to live. We can model how getting scared to death would affect my lifespan with the following equation:
L = 59*(1/2)^n
L being the years I have left to live, and n being the number of times I've been scared half to death.
So we can use algebra to figure out (roughly) how many times I have to be scared half to death to reach a remaining lifespan of .25 secs and therefore die almost instantly.
.25 secs is hard to convert to years, but I did it anyway: it's 1/(365*24*60*60*4), or 7.92744799594*10
-9So, therefore
(1/(365*24*60*60*4)) = 59 *(1/2)
nand n = log
1/2(1/(365*24*60*60*4*59)) = n
n = 32.79
That means if I wanted to guarantee that I wouldn't be able to have any kind of perceptible experience of life after being scared half to death enough times, I would want to be scared half to death 33 times.
