A 92-year-old Holocaust survivor describes his secrets to longevity and happiness

Ed Mosberg was born in Krakow, Poland in 1926. He survived Płaszów and Mauthausen concentration camps. He lost his entire family in the Holocaust. Here, he reflects on the meaning of life and what's gotten him to 92.

Ed Mosberg: There's only one thing. You should stick with your family and with your friends. This is the most important thing in your life, when you stick with your family and with your friends.

And like I always say to my wife, we are one life and we are here together. I do every day, making push-ups, sit-ups, hydraulic steps, I run on a treadmill, because I have to be fit for my wife. Anytime she need me, that I am there for my wife. This is my primary thing. Like this morning, I got up, I was 5 o'clock up this morning and I was on a treadmill. I make all the other exercise.

It's not a secret. Just be active. Not to overeat, okay? Because this is the worst thing. People are overeating. They say, "Well, I'm hungry." You can control it.

I tell you what I had this morning. This morning I had a glass of water, cup of coffee with plenty sugar and half a small yogurt. Yogurt, the small one, I take a half. And that's all. And if I don't have a lunch, I can go like this 'til the evening so long I have a cup of coffee. I don't want you tell my daughter what I eat.

This is not a secret to live to 92 and I tell you now, I already decided, I have a party when I will be 100. I have the date already.
