Green Bay Packers quarterback Aaron Rodgers is one of the best in the business, and he expects to stay that way for a long time. Rodgers, who turned 30 in 2013, recently started paying closer attention to his health. These days, he’s eating better, getting more sleep, drinking more water, and taking better care of his body. The result? Rodgers is on fire this season with the Packers. And with his new healthy habits, he believes he could play into his 40s.
