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

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.

I think guys overtrain and they burn out. And also just knowing what your body needs. Again, I think rest is really important.

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.

I think that while kids are in college they don't think that fitness and nutrition are really important things. But once they get to the NFL it's a job, and just like any other job you've got to be at your best to a certain point, especially with a job like this. You've got to be fit and you've got to eat the right things.

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.

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.
