Of course not. I plan on using one or the other, or possibly some third one they come out with later, for a total of THREE TIMES that length of time, assuming I live to see ninety.
But I have reasonable faith that in the next fifteen years, the prices of not-grey will go down enough that I won't have to live under a risk of "some day, I might find myself in a situation where my finances are too tight to afford the meds that keep me from gaining back all sixty-seventy pounds I lost and then some, and I might be looking down the barrel of white-knuckling through life against that kind of issues with food that I fought so hard with in the first forty-five years and always ultimately succumbed to."
