Well, I do have to start there, but, actually, i wanted to go different way. I will argue that immortality has different value given the different information and preferences we have.

(Because, it's not 1 + r + r^2... it's v(0) + v(1) r + v(2) r^2 +.... where vx is value we obtain in x-th year of our life. This can converge or diverge, it is dependent on our evaluation of v's and ofc. r.)

Also, please don't split it to multiple articles; and if you really have to, then please put something interesting in the first article already, don't make it merely a teaser.

Thank you for advice, I will give my best to make it short and interesting. Though not at cost of making it unclear and therefore useless.
