Guys are faster, they're bigger and they're stronger. I think that's probably the main thing. And that's not just in football, I think it's in every sport.

I think as you get older and things don't work as much as they used to, you've got to have a tendency to do what's right for your body.

Your diet has to be number one. If you don't eat the right things, it doesn't matter who you are. Sometimes those foods treat people differently.

Guys get injuries and there's a reason why these injuries happen. A lot of time you're going to get your knee injuries and your ankle injuries, but sometimes if a guy's back is hurting it might be because his core isn't balanced with his back.

A lot of times I go to the gym and I see people and they don't know how to work out. There's no routine or anything like that. I saw a guy who I haven't seen in five years and the guy looks the same as he did five years ago.

When you are younger you tend to overtrain and you don't realize it because you're so high on adrenaline and stuff.

When I came into the league in '85, the regimen for working out was just basic, and as I got older it became more about the core and keeping your body in balance.
