A retirement plan built for a long life looks very different from one built around a short retirement. If someone knew with absolute certainty that they would reach 100, suddenly every early-retirement splurge, oversized house, aggressive withdrawal, and “deal with it later” financial decision would deserve another look.
That thought experiment can expose weaknesses hiding inside an otherwise respectable financial plan. It can also reveal something encouraging: planning for a very long life does not mean living like a monk who has personally declared war on vacations. It means giving money more jobs, more time, and a little more breathing room.
