MATH LITERACY
The investment income graph displays the true magic of exponential growth: The income is limited when Joe's a young guy,
but as he gets closer to thinking about retirement, the income really takes off. Notice that at age 65, something awesome hap-
pens: The income that Joe's making from his investments is more than his living expenses. At that point, he can retire and live
as well as ever without, you know, working for a living. Sweet! This age is known in financial circles as the crossover point.
