But, mostly the amount they increased by went down as the current length of time went up. Which seems to indicate a diminishing return.
I think that most current medical technologies are merely increasing our lifespansd towards our natural limits. I look forward to the future treatment that increases those limits dramatically (or removes them entirely).
