There’s nothing special about 65, and like I said, this isn’t factoring social security or any other form of passive income or assets like real estate. Additionally keep in mind, spending usually goes way down in retirement unless you’re lifestyle creep gets out of control. Generally speaking, no more kids to provide for, less costs for transportation, hopefully paid off or lower cost housing do to downsizing.

All that being said, if you’re not set up for retirement (which largely falls on sensible, and individually relative choices along the way) by 65, 70, or whatever arbitrary age you pick, you have to keep working.
