Presidents have been known to take on hobbies after their tenure in the White House is over -- like George W. Bush and his paintings. Former President Jimmy Carter has started an interesting habit when he flies: shaking everyone's hand.
"His enthusiasm was authentic and humble, in a way that made things feel less heavy for a moment," Sheffield told WSB-TV.
Carter's actions also captured hearts on Twitter, where the video received over 13,000 retweets and 35,000 likes.

Jimmy Carter of Plains, GA, was the 39th President of the United States and a big fan of NASCAR racing. In 1978, Carter invited a number of NASCAR Cup stars to the White House for a big dinner and entertainment provided by country star Willie Nelson. Nelson was there and so were First Lady Rosalynn Carter and the President's brother Billy Carter, but President Carter was nowhere to be found. The President had gone to Camp David to meet with the leaders of Israel and Egypt, Menachem Begin and Anwar Sadat, in what ultimately would lead to a huge Middle East peace agreement known later as the Camp David Accords.
