Unlike his TV character, actor Dean Cain (Princeton) is not immortal. He has aches and pains just like the rest of us, due to his football-playing days at Princeton University. The actor first rose to fame as the star of "Lois & Clark: The New Adventures of Superman" with Teri Hatcher. Now, at age 52, he's hoping to stop the hands of time with the help of stem cells and the Beverly Hills Rejuvenation Center, where he receives treatment and is a brand ambassador.
