If you don't listen to the Public Radio program RadioLab I can't quite say that you're wasting your life, but I can say that I'm worried for you. I think it's easily one of the most interesting and creative examples of radio journalism anywhere.
One of its hosts is renowned science journalist Robert Krulwich, who last summer gave the commencement address at Caltech. If you write about science, I think it's well worth a listen.
