Dale Earnhardt Jr. turns 40 years old

Dale Earnhardt Jr. is celebrating his highly anticipated 40th birthday as he prepares to race at his home track in Concord, North Carolina on Saturday. Earnhardt, an 11-time most popular driver in NASCAR's top series, has rebounded on his performance in the past couple of years after a somewhat slow start with Hendrick Motorsports and is once again a competitive driver, like he was with Dale Earnhardt Inc. in both Nationwide and Cup. Now that he is 40 years old, some fans say he isn't exactly a "Junior" anymore, even though most people still prefer to call him by that nickname.
