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.

There are so many things out there now like these 30-minute workouts. I don't know if they work, but a lot of people have jobs and they don't have time to go to the gym. They can do those little 30-minute workouts they see on TV, or get one of those little portable gyms for their house. I think that's a good start.

Some guys don't have to work out as hard as other guys do, but if you balance all that together then your longevity is definitely going to be greater. So, I would tell my 20-year-old self not to over-train.

I was a gym rat and I always thought that was a part of my success.

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.

I usually eat anything I want. I'm not a big junk food guy, really.
