As Biden becomes a member of the former presidents club, here are a few suggestions for his retirement to-do list.

WASHINGTON (NB360) — President Joe Biden is about to have more free time than a kid during summer vacation. For retirement inspiration, he just needs to peek at the past presidents' playbooks.

At the ripe age of 82, Biden is the oldest U.S. president. In a recent chat with USA Today, he admitted he’s not sure how sprightly he’ll be at 86, saying, “Who knows what I’m going to be when I’m 86 years old?”

But age is just a number for ex-presidents, nine of whom partied past 90. This list includes George H.W. Bush, Gerald Ford, Ronald Reagan, John Adams, Herbert Hoover, and Jimmy Carter, who recently hit the century club.

Here’s a peek at some classic — and some downright wacky — ways Biden might spend his golden years:

Plot to boost his historical street cred

Unlike his predecessor-turned-sequel, Donald Trump, Biden probably won’t be staging a political encore.

The Democrat has been mum about his post-presidency plans. Those who know him well say it’s a topic he’s reserved for his inner circle of trusted sidekicks.

Some modern ex-presidents have raked in big bucks from speaking gigs. Biden, who spent much of his term battling low approval ratings, could use these gigs to pump up his legacy and future fan club. He told USA Today he hopes to be remembered for “restoring the economy and reestablishing America’s leadership in the world.”

The silver lining for Biden is that presidents often get a popularity boost after they exit the spotlight.

Republican George W. Bush left office with a popularity score lower than a limbo stick during the Iraq War and financial crisis. Yet, he became more beloved later, despite keeping a low profile while dabbling in painting. Trump also dealt with low ratings throughout his first term but managed a comeback to the White House in November.

Raise funds and sketch out a presidential library

Biden’s likely to prioritize fundraising and drafting blueprints for his presidential library. It would probably pop up in his home state of Delaware, where he served as a senator for 36 years and spent many weekends as president.

Officials have already recruited at least one Biden administration ambassador to help with the fundraising hustle. A model to consider is the Barack Obama Presidential Center, a sprawling 19.3-acre library and museum in Chicago. Construction kicked off three years ago, with a finish line in sight for 2026.

Sort through keepsakes — with care

Word on the street is Biden’s a bit of a hoarder, and he might want to cling to mementos from his White House days. He’ll need to tread lightly.

Federal elected officials must hand over official documents and classified materials when they leave office. Biden’s personal lawyers have been carefully managing documents ever since classified materials from Biden’s Senate and VP days were discovered at the Penn Biden Center in Washington and in his Delaware garage.

These findings followed an FBI search in 2022 at Trump’s Florida club, part of a documents case that fizzled out after he reclaimed the White House. In Biden’s case, special counsel Robert Hur later published a report questioning the president’s age and mental sharpness but didn’t pursue criminal charges over document mishaps.

“We are going to do our best, certainly, to be careful to follow the rules, to do this the right way,” White House press secretary Karine Jean-Pierre said when asked about document retention on Friday.

Write another memoir — cautiously

Biden hasn’t shown much interest, insiders say, in penning another book. He’s already written two memoirs, “Promises to Keep” in 2007, and “Promise Me, Dad” in 2017.

He might eventually decide to work on a third, to further cement his legacy. Again, he’d need to be careful.

Hur accused Biden of being a bit loose with classified info with ghostwriter Mark Zwonitzer, who helped with Biden’s first two books. The special counsel considered charging Zwonitzer with obstruction of justice because the ghostwriter destroyed recordings of interviews with Biden while working on his second memoir.

Ultimately, Hur’s report said Zwonitzer had “plausible, innocent reasons” for doing so and later cooperated with investigators.

Join the ex-presidents club

A fan of political tradition, Biden could embrace the ex-presidents club. These former commanders-in-chief occasionally pose for photos and exchange pats on the back at historic events — and sit together at VIP funerals.

Former presidents sometimes team up for special projects like promoting vaccines during the COVID-19 pandemic or raising funds after natural disasters. They rarely criticize each other and are even less likely to throw shade at current White House residents.

This will give Biden a chance to stand out from Trump, who showed little interest in mingling with ex-presidents after his 2020 loss. He also skipped typical post-presidency projects like building a presidential library, focusing instead on his 2024 campaign.

Biden already formed his own version of a former presidents club while in office: He prepped for his State of the Union address last March by holding a video call with actors who had played presidents.

Morgan Freeman, Tony Goldwyn, Geena Davis, and Michael Douglas offered advice and encouragement, as did Bill Pullman, who played President Thomas J. Whitmore in “Independence Day.” Pullman seized on Biden’s constant optimism, predicting, “People, when they look at all that you’ve managed to do, they’re gonna remember. Time will remember, always, your words.”

Try his luck in showbiz?

Speaking of celebs, Biden’s hinted at more glamorous post-presidential pursuits.

In August, about a month after he nixed his reelection bid, Biden joked at an event for online content creators: “That’s why I invited you to the White House — because I’m looking for a job.”

When Jessica Alba helped celebrate Hispanic Heritage Month at the White House a few weeks later, Biden quipped that he might soon need the star’s business connections to find work, saying, “Jessica, if I’m really good, maybe you can get me a job?”

He cracked a similar joke at a December event for Kennedy Center honorees, telling Robert De Niro, “If I get in trouble, I’m coming to you, pal.”

“I’m looking for work in February,” Biden said to laughter. “Maybe you’ve got something for me? A Biden-De Niro combo? I can’t sing, I can’t act, I can’t dance, do a damn thing – but I could help ya.”
