I thought about this and I can construct some logic to support his phrasing. Suppose we figure out how to end aging, but people continue to die at the same mortality rate as the 25-34 year old group. That's roughly 1/1000 per year. (999/1000)^692 = 0.5 If we could nudge that mortality rate down a bit, 800 seems like a pretty good ballpark estimate.
