A kid who moves is a kid who learns.

I start phone calls at 4 A.M. to cheer people up. The housebound, people in the hospital. People who, after decades, still can't get over what happened 10 or 15 years ago.

What if you can't do what you once did, like run and jump up and down? You can walk, which is also good for your mind and mental attitude. You can do simpler exercises, like getting up and down from a chair without using your hands. You can stay fairly flexible. The most important thing is to not become sedentary.

I have been up to my head just with calling people, I call about 50 to 100 people a day.

I sort of think of myself as part priest, part clown.

Energy is that amazing feeling that comes to life inside of you when you're happy and believe in yourself.

Most workouts are way too aggressive. Thousands of lunges wear out the body. It's not healthy for the one with the bad back, bad knees, diabetes. I'm never going to do that.
