After seeing The Rolling Stones in concert over the weekend, I can confidently say the short answer is "no."
We need to be thinking about age and rock music in a different way. When I was in my 20s, my generation thought 30 was too old for a rocker. Now, in 2012, the brilliant futurist Ray Kurzweil is wondering who the first person to be 150 will be. He told a crowd at the 6th and I Synagogue in Washington, D.C., that he thinks that person is alive today.
