Actuarial Escape Velocity

At the moment, life expectancy in the United States increases at the rate of one year every five years. In other words, it takes about five years for life expectancy to increase one year. The longevity-related term actuarial escape velocity refers to the point at which human life expectancy increases at least one year for every passing year. At this point, human lifespan is increasing (on average) faster than the onset of death.
