"The reason I say 45 is the turning point, or in your 40s, is because, think about a career: Most careers start in early 20s and end in the mid-60s," O'Leary said.
"So, when you're 45 years old, the game is more than half over, and you better be out of debt, because you're going to use the rest of the innings in that game to accrue capital."-------
