Started BJJ at 47: An Economist's Case for Aging on the Mats

Most people spend their late forties looking for reasons to slow down. Roggiero J. Spillere went looking for a Jiu Jitsu academy instead — and the economist, professor, and now BJJ black belt has turned that decision into a new book arguing that Brazilian Jiu Jitsu is one of the best tools we have for aging well. It's the kind of story we love around here, because it lands squarely on a question every gym in the world quietly wrestles with: is this a young person's game, or is it something you can build a whole second half of life around?

Spillere's résumé reads nothing like a fight-camp bio. He's a professor of economics and a doctoral student in law and policy, a retired global executive who has written on globalization and social justice. Then, at 47 — an age when plenty of practitioners are already talking about "hanging up the gi" — he tied on a white belt and started over from zero. Years later he's a black belt with a framework, laid out in his new book, for how to train Jiu Jitsu productively well beyond midlife. The report on the book comes via The National Law Review, and the pitch is refreshingly unglamorous: not medals, not the podium, but staying healthy, sharp, and capable as the decades stack up.

Why Jiu Jitsu keeps showing up in the aging conversation

If you've spent any time in a BJJ gym, none of this will surprise you. The mats are one of the few places in adult life where a 55-year-old and a 25-year-old routinely compete on the same square metres — and where the older person often wins. Jiu Jitsu rewards timing, leverage, patience, and problem-solving over raw explosiveness, which is exactly the trade you want to be making as you age. Strength fades on a predictable curve. Understanding compounds.

There's a growing pile of research pointing the same direction, tying grappling to better balance, cardiovascular health, bone density, and — maybe most importantly — the kind of social connection that keeps people showing up week after week for years. But you don't need a study to feel it. Every academy has its grey-bearded professor who moves like water and taps people half his age without breaking a sweat. What Spillere is really doing is giving that familiar figure an intellectual backbone: an economist's framework for treating your training like a long-term investment rather than a young man's gamble.

The lesson for the rest of us on the mats

Here's the part worth sitting with. The single biggest reason people don't start Brazilian Jiu Jitsu in their forties and fifties isn't their body — it's the story in their head that it's too late. Spillere is a walking rebuttal. A guy with a demanding academic career and zero martial arts background walked in at 47, respected the process, and came out the other side a black belt. Not a prodigy. Just consistent.

And for those of us already training, the message is arguably more useful still. Longevity in Jiu Jitsu isn't luck — it's a set of choices you make every single week. It's tapping early instead of defending a locked submission to prove a point. It's choosing your rolls, picking your partners, and knowing when a hard round costs more than it's worth. It's building a game around leverage and position instead of the athletic scramble that ages out from under you. Framed that way, "training smart" stops being the consolation prize for getting old and becomes the actual skill — the thing that lets you keep doing this at 60, at 70, and beyond.

That reframe matters because Jiu Jitsu has a quiet attrition problem. Plenty of talented people burn out or get injured chasing intensity that was never sustainable. A framework aimed at the opposite outcome — decades on the mat, not just a hot competitive stretch — is exactly the message the average practitioner needs more of.

So the next time your knees complain on the drive to the gym, or you catch yourself wondering whether you're too old to start, remember the economist who ran the numbers and concluded the smart money was on getting on the mats. The gentle art was designed for exactly this — a smaller person, an older person, a tired person, finding a way to keep going when brute force runs out. That's not a loophole in Jiu Jitsu. That's the whole point of it.

See you on the mats.
