After 26 years, I am still practicing what I preach.

I used to think that it didn't make any difference how far you ran if you had a good, strong musculoskeletal system and no underlying cardiovascular problems.

Aerobic dancing is already adjusting to injury problems and will probably phase out to some extent.

I don't criticize weight training - as long as it is not a substitute for aerobic training.

I think investments in general related to the exercise industry are going to be good for a long time.

Since then, I have not missed five consecutive days in getting some type of aerobic exercise, mostly jogging.

According to the Gallup Poll, 24 percent of American adults exercised regularly in 1961, and 50 percent after 1968. The peak was 59 percent in 1984, dropping off to 51 percent last September.

So I've broadened the fitness concept to make it one of moderation and balance.

The reason I exercise is for the quality of life I enjoy.

Now I say that if you run more than 15 miles a week, it's for something other than aerobic fitness. Once you pass 15 miles, you do not see much further improvement.

If you look at body fat, it seems to increase with age, even though your weight does not. That's a physiological fact of aging, they say. Heck it is. It is an adaptive effect of aging.

Over the years, I've covered 22,000 miles.

After 26 years, I am still practicing what I preach.

There are six components of wellness: proper weight and diet, proper exercise, breaking the smoking habit, control of alcohol, stress management and periodic exams.

We are involved in youth testing internationally. We want to try to prove without a shadow of a doubt the relationship between physical fitness and health, not just physical fitness and ability to perform.

You have to run 75 to 100 miles a week if you expect to break the four-minute mile.

Far too many times over the next 12 to 15 years, it was brought to my attention that people who followed my exercise guidelines exactly but ignored their diet, their weight and their cigarette smoking had heart attacks at age 55.

I have not missed a day from work because of illness since 1956.

I was surprised that the TV series was popular itself, but after that it went on to become more popular over the years and thus it seemed eventually that they would turn it into a movie.

I prefer to remember the happy things over 10 years, the things that went well. Let me see, what did go well?

What I try to do for my readers is to pass on some of the things that I found out about being thirteen after doing it for forty years.

I think I've become a much better singer and a much better player. Years and years of playing a couple of hours every day will do that.

There is no need to do any housework at all. After the first four years the dirt doesn't get any worse.

The robe of flesh wears thin, and with the years God shines through all things.

The Republicans claim they are for strengthening Pell grants when the truth is that over the last four years, their legislation has done the exact opposite.

I want to thank all the fans for their support over the years. Keep supporting the Knicks, we're moving in the right direction here and we will be exciting to watch and competing against the best in the NBA. Come back to the Garden for those exciting games.

I am told that there have been over the years a number of experiments taking place in places like Massachusetts Institute of Technology that have been entirely based on concepts raised by Star Trek.

I couldn't sleep for two years, they tried to break my nerves. They used a lot of psychology to brainwash.

What the war did was give me the opportunity of three years of continuous reading, and it was in the course of reading that I became convinced that I should become an economist.

You look at the whole Human Rights questions, I happened to be there at just the right time when the country was awakening - this goes to the first question you asked - the whole country was awakening to a hundred years of injustice that hadn't been resolved yet.

We started filming in 1993 which was only four years after the fall of communism. The difference in Budapest over the last five years has been remarkable.

I had a wonderful time with the Stones but after 31 years, I thought it was time to move on.

The average life spans of many bands are not that long, up to five years if they are lucky.

For years the Trio did nothing but play for musicians and other hip people. We practically starved to death.

Had the Hebrews not been disturbed in their progress a thousand and more years ago, they would have solved all the great problems of civilization which are being solved now under all the difficulties imposed by the spirit of the Middle Ages.

There is no rational reason to doubt that the universe has existed indefinitely, for an infinite time. It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.

Plan Colombia was supposed to reduce Colombia's cultivation and distribution of drugs by 50 percent, but 6 years and $4.7 billion later, the drug control results are meager at best.

So the guy that we're really targeting our system at this year is one of the guys who brought a 16bit system three or four years ago and has pretty much had it with that, and he's ready to buy something new.

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.

I have everything I had 20 years ago, only it's all a little lower.

Confidence comes from hours and days and weeks and years of constant work and dedication.

In the past 3-4 years I've developed a habit of keeping numerous small cassette recorders in my house and in a bag with me so that I'm able to commit to tape memory song ideas on a constant basis.

I've been a financial journalist for 30 years.

If Davis Cup was a little bit less or once every two years, I would be more inclined to play. But the way it is now, it is too much tennis for me.

I'd been trying for all of the eight years we'd been married to have a child, and finally I did.

I don't shop. I haven't shopped in about four years.

Yippee! I can't believe I made it. It feels like a long haul to get here. I'm so fine with it. People want you to have some sort of breakdown, but I'm relieved to be 40 years old, and I've lived a life.

It wasn't my plan to create such a record. All I did was put in the effort to win every match I played and it went on for weeks, months and years until my defeat to Ross Norman in Toulouse in 1986.

That was really cool. I got to kiss a little boy. I was 7 and he was 10, and his name is Thomas Curtis. He was the first boy I've ever kissed in my entire life and he was three years older than me.
