Stockton environmentalist Bill Jennings has this habit of wearing his glasses on his forehead, which is fine but I don’t know how he manages to keep them up there without them constantly sliding down. Sometimes they look as if they’re permanently affixed until he reaches up to bring them down. Jennings spoke at the protest against the governor’s proposed tunnels that would bypass the Delta. His glasses with the round frames were perched above his brow as usual but he also wore a ball cap. You’d think that would force the glasses off of his forehead. But no, the frames stayed true. How does he do it?
