The Usable Years

Every retirement book asks the same question: how much money do you need? This one asks a different one — how much body do you have left?

The Usable Years is built around a simple idea most people never sit down and think through: your lifespan, your retirement years, and what Brian calls your "usable retirement years" are three completely different numbers — and the gap between them is the whole point of retiring well. You could retire at 62 with 25 genuinely good years ahead of you, or you could retire at 62 and get five. The only way to find out which one you got is to live it — which is exactly why the question is worth asking now, not later.

Written by Brian W. Darling — retired at 50, debt-free, and now traveling the world and documenting it on Lifing With Brian — this is part memoir, part wake-up call, drawn from his own family history, his own mistakes, and his own honeymoon-phase-to-real-life retirement.

What's inside:

• The 1.0 / 2.0 / 3.0 framework for thinking about who you were, who you became, and who you still get to become

• The real math on retiring at 62 vs. 70 — including the cost nobody puts on the spreadsheet

• A framework for figuring out your own "usable retirement years," grounded in family health history, not guesswork

• The honest, unfiltered version of year one of retirement — the bucket-list spending panic, the friendships that change shape, and what nobody tells you before you get there

• A way to build real structure into days that no longer come with one built in

Who it's for: anyone thinking about retirement, anyone freshly in it and feeling adrift, and anyone a few years in who suspects they've quietly started coasting.
