The Super Bowl 56 halftime show was a match made in millennial heaven. It was about time they moved on from Bruce Springsteen and The Rolling Stones and brought in some music for the younger generation. Oh, wait. Sunday's epic performance that included hip-hop icons Dr. Dre, 56, Snoop Dogg, 50, Mary J. Blige, 51, Eminem, 49, 50 Cent, 46, and the "baby" of the group, Kendrick Lamar, 34, served as a harsh reminder that the Gen X and Gen Y generations are old now.
