How much would you be willing to spend on life-extension applications?

Whether it’s medication, diet and lifestyle changes. Going vegan, exercising daily, and say telomerase treatment.

Would you invest in current anti-aging research to shorten the time-to-application?

Methuselah foundation has an active support program for relevant research. http://www.mprize.org/

Keep in mind the question was originally “anti-aging” which is a main cause for shortening life spans. Aging itself has many variables, only of of which is cell biology and telomeres. So try to disregard the off-topic questions and answer anyway :)
