It’s arguably the world’s most exclusive club, so it’s not surprising that its members look out for each other.

When Jimmy Carter was felled by dehydration at a Habitat for Humanity building site Thursday, two of his fellow former presidents of the United States were quick to let him know they had his back.

Hours after the 39th president was hospitalized out of precaution in Winnipeg, Manitoba, the 42nd president, Bill Clinton, tweeted out his good wishes:

So did the 41st president. George H.W. Bush, who, in his pre-Oval Office days,  as C.I.A. director, traveled to tiny Plains, Ga., to brief Democratic presidential nominee Carter in 1976,  used his spokesman's Twitter account to send good thoughts No. 39's way Thursday:

No doubt Clinton, 70, and Bush, 93, were heartened by Friday morning's news that Carter had been released from the hospital and made his way back to the Habitat building site.

Carter, 92,  and his wife, Rosalynn, 89, attended the 8 a.m. morning devotional at the Winnipeg site on the fifth and final day of the 34th Habitat for Humanity Jimmy & Rosalynn Carter Work Project. From July 9-14, the Carters have joined thousands of volunteers on a blitz build of 150 homes across Canada in celebration of the country's 150th anniversary. The former first couple, who last week celebrated their 71st wedding anniversary, spent Monday through Wednesday working on the building site in Edmonton, Alberta, then moved on to Winnipeg for the last two days of the high-profile project.

Former President Jimmy Carter became dehydrated on a Habitat for Humanity build in Winnipeg Thursday morning and reportedly received medical attention.
