Alex’s odds of living longer are improved by LOOKtoLIVE, but how many additional years can he gain? The chart shows the number of years of Alex’s life that will have been saved by a given age. In that first year, age 50, Alex gains 0.2 years, or about 2.4 months. He accumulates additional years saved as he ages, so that by age 85 he has amassed about 8 additional years of life.
One of the most interesting features of this relationship is its linearity. Over a wide range of ages, LOOKtoLIVE improves survival by about the same amount each year. Alex begins accruing his survival advantage in the first year, and gets the same additional advantage each year thereafter. The sooner he joins LOOKtoLIVE, and the longer he participates, the more he improves his odds.
