Will 250 be the new 100 in the foreseeable future? Human life expectancy has made steady gains over the last two centuries, and anti-aging scientists seeking to spare human cells and DNA from the corrosion once deemed inevitable are eager to trigger a radical extension in our life spans. How likely is such a spike? And how desirable is it to live to be a quarter of a millennium? Will life-extending scientific breakthroughs translate into an interminable twilight for many, or will they also postpone aging?Please join us to learn about the state of life-extending research, and to ponder some of the wrenching philosophical, societal and actuarial (et tu, Social Security?) questions raised by the efforts to radically grow life expectancy.
