A photo of President Joe Biden and first lady Jill Biden alongside former President Jimmy Carter and his wife, Rosalynn Carter, is making waves online. The Bidens look gigantic next to the Carters, who appear oddly smaller in comparison. A White House photographer snapped the photo when the couples were visiting the Carter home in Georgia last week, prompting thousands of comments. So what is exactly going on here? One theory is that the Carters, 96 and 93, have become smaller in their old age. #InsideEdition
