Robert Frew is 92 -- and he is finally ready to retire for real. He started working as an elementary school crossing guard in Florida when he turned 75, after retiring from the phone company. He was only going to do it for a couple of years, but "it gets into your blood," he says, and so he kept coming back year after year. On his last day, the school community turned out to celebrate Mr. Bob, as he’s affectionately known, and to proclaim June 4 as Robert Frew Day.
