"Hi, I'm John. I'm from Dallas, Texas. My wife's name is Joy. We've been married 45 years and have three children and four grandchildren. And the fifth one on its way."

"I've been producing and directing for get this, over 50 years. It's a very detailed thing and the pressure's all on me. And so I need to be alert. I need to be sharp. I really don't like being on this side of the camera."

"I'm taking a two year business course. I've been studying a lot, maybe an hour in the evenings, maybe two or three nights a week. I really try to eat healthy. I try to work out three or four times a week when I can. I like lifting weights. I work on the treadmill and I do the bike in the gym where there's air conditioning. I don't eat any grains or sugars unless once in a while with the grandkids."

"Around 10, 15 years ago, I noticed I really wasn't quite as sharp as I was at work. I was kind of missing things. I was really kind of getting concerned because everybody was saying, oh, everybody goes through this, so you're just getting old."

"My boss told me about Prevagen. As soon as he told me about it, I thought, wow, this sounds like a really good idea. And I started taking it and then I noticed a change. I feel sharper, I feel alert. My memory's a lot better. Pretty excited about that. I've been taking prevention for at least 10 years. It just works. That's all I can say. It just works."
