TextThe American definition of success is largely one of acquiring wealth and a high material standard of living. It is not surprising, (1) , that Americans have valued education for its monetary value. The belief is widespread in the United States (2) the more schooling people have, the more money they will (3) when they leave school. The belief is strongest (4) the desirability of an undergraduate university degree, or a (5) degree such as medicine or law (6) the undergraduate degree. The money value of graduate degrees in (7) such as art, history, or philosophy is not (8) great.This belief in the monetary value of education is (9) by research outcomes on income. Ben Wattenberg, a social scientist, estimates that in the (10) of a lifetime a man (11) a college school diploma in 1972 could earn about $380,000 more than a man who (12) had a high school diploma. Perhaps this helps to explain survey (13) which showed that Americans who (14) they had lived their lives differently in some way regretted (15) of all that they did not get more education. The regret is (16) by those who have made (17) to the top and by those who have not. (18) a man like Douglas Fraser, the president of the United Auto Workers Union, a nationally known and successful leader, was (19) by regrets that he did not climb higher on the (20) ladder. 6()

Eufracio Tolentino:I did regular exercise when I was young, but by my 30s, I had a family and a busy job. I neglected exercise for years. At 59, I had a stroke that resulted from lack of exercise. Now I visit a recovering center in the morning and spend my afternoons exercising. I encourage my friends a start exercising. If they don’t, engaging too much in their work or family, they may also suffer from a stroke.Raymond Chiew:Think you’re healthy just because you’re within your ideal weight range for your height Wrong! Take me as an example. I figured I got enough exercise playing tennis once a week, for I wasn’t overweight and didn’t smoke or drink. Then at 57, I woke up one early morning with chest pains and tests revealed that I had serious heart trouble. I was shocked. Now I walk for an hour every day and my doctor says that my heart is improving.Dr Santos-Ringor:Whether you hire a personal trainer, take exercise classes at the community center or rent exercise videos, spending money on fitness is really money well spent, for health is wealth. But if you can’ afford any of those, just get a comfortable pair of shoes: walk is free. I form an exercise group with friends, play catch with my kids or set aside Saturdays for long walks in the country.Ruth Cheah:You’re never too late or too out of shape to start exercising. I didn’t start to exercise on a regular basis until I was 59. Now, as old as 79, I take a daily 45-minute walk, go swimming twice a week. These exercises free me from medicines, and I feel active and alert. People tell me that I look younger than my age.V. M. Chandran:Many people start exercising because they want to lose weight, and when that doesn’t happen immediately, they may give up. But the same volume of muscle weights more than that of fat, so a large person who is fit could be healthier than a thin person who is not. When I saw my weight rise past 90 kilos in my late 40s, I began taking walks for 45 minutes a day. Even though I still weigh over 90 kilos, I feel much stronger. I’m proud to have muscles, not fat.Statements Ruth Cheah()
