10.73 months from now seems about right.
Quoting MENSA mag cover entity jcl, but corrected some smelling.

Suppose you can now decide your natural life span, but can not reverse that decision once it's made. The speed of your aging will then be determined by the desired year of your death. If you want to die within the next 10 years you'll age very fast, but when you want to die in 200 years or later, you'll age very slow or not at all. In which year do you want to be dead?



Above, I replied before properly digesting the quoted material, but oh whell, it's too late now.
The question is seemingly too one-sided, with too much con on one half the mark. Perhaps, it's a coded prompt for planning group activities, or a quick, simpleton weeding device? Basically, take a little off the top and make me smell like a flower.
