 You won't believe how old this couple is. Excuse me? I ask people who are in really good shape what kind of diets they're on. Do you mind if I ask what types of food you usually eat? Sure. We really just eat anything we want. Pretty much anything. Wow, you both look great. Do you mind if I ask how old you are? I'm 64. And how about you? I'm 59, almost 60. No way. So what's your secret then? What do you do? Tell them. All right, this is going to sound a little weird, but
