Muhammad Yunus just had a milestone birthday. On June 28, he turned 75. It's a big moment for a man who's had many big moments in his life — most notably the 2006 Nobel Peace Prize for founding Grameen Bank, which loans small sums, aka "microcredit," to the poor, mainly women, so they can start their own businesses.
Yunus stopped by NPR last week — he was in Washington, D.C., for a conference — wearing the long, open-necked "kurta" shirt of his native Bangladesh. "[A tie] looks funny on me," he joked.
