While meandering the byways of the internet, I came across a rather nicely done promotional video short for the work of the SENS Foundation. I don't believe it is in any way authorized, but it's the sort of simple, quality product that this community excels in producing. Take a look and see what you think.
More on the Methuselarity as a concept, and how it relates to longevity escape velocity, can be found back a little way in this year's Fight Aging! archives. At some point, the advance in biotechnology and its applications to medicine will begin to add more than one year of remaining life expectancy with each passing year of progress - at which time everyone who can make use of these technologies of longevity will be functionally immortal. Vulnerable to accident and ill will, but no longer aging to death.
This goal lies a way away yet - largely because the research and development community required has yet to be assembled. This is far more a matter of organization and persuasion at present than a matter of getting the job done. In order to get the job done, you need a sufficient number of workers and the investment of resources to fund their research. Making this happen is today's challenge.
