questions 61 to 65, match the name of each person, to one of the statements(A to G) given, below. Mark your answers on, ANS WER SHEET 1.

Lee Beaty:

Your "Health For Life" articles give excellent advice on simple lifestyle. changes to improve

health. Whenever possible, I ride my bicycle to work. While I was a student, I also rode to class.

We need to educate motorists about sharing the road with cyclists, and create bike lanes to encour-

age more people to go from point A to point B while getting some exercise, saving fuel and impro-

ving the environment.

Roberto Anson:

You had a fascinating exploration in your " Health For Life" articles. Technology often makes us give up responsibility for our health. The United States has the best medical technology but une-qual access to care. The point is that, increasingly, only the healthy and well-off can affOfd health care. Your advice to skip the heart scan and spend the money on a health club membership shifts the focus from technology to personal responsibility.

Fred Leeds:

Dr. Nancy Rigotti 's "Kicking the Habit" is tried, but not necessarily true advice. As a for-mer three-pack-a-day smoker, I tried these approaches many times with no success until I finally accepted a fundamental truth about myself. Only after I got my mind set to the point where my de-sire to quit smoking was stronger than the desire to continue was I able to put the cigarettes down.

Bill Wittig:

It is well documented that people with the Type D personality have chemicals in their brains that differ from those of normal people. Many of them never get mental health treatment because they work, have families and by all observable criteria are functioning well. They do not realize their problem. What might prevent the Type D personality from having a heart attack is some psy- chological treatment as well as fish oil.

Kristin Linklater:

Your magazine tells me that not only must I exercise to avoid heart attacks, but I must be hap-py. I must laugh a lot, or my heart will be starved of necessary chemicals. I must have friends and community to support me, or I'll certainly die soon. I tried to take the Type D personality test that will determine whether I'm going to die of negativity, but your column headings, "False, Less false, Neutral, Less true, True, "make it impossible to figure out my behavior.

Now match the name of each person, (6/ t0 65) to the appropriate statement.

Note: there are two extra statements.

Statements

[A] You can hardly force yourself to do a thing until you feel likedoing it

[B] Mental health treatment may help prevent some physical prob-lems.

[C] We' d better count more on regular exercise than medical care.

[D] I"m not interested in taking any behavior. test proposed in magazines. [E] Cycling is good for health as well as for our surroundings.

[ F ] To save money and improve health, I quit driving to work.

[ G] I'm still puzzled as to whether your advice and the listed personality details suit me or not. 61. Lee Beaty
