Betty is a professional high diver and takes a vacation to a beach she has not visited before. while there, she notices a tall cliff, which she thinks would make an excellent place to practice her diving. which of the following statements about this situation is false? a. it would be safer for betty to practice at home since she is unfamiliar with the area. b. it would be perfectly safe for betty to swim around and make sure the water is deep enough. if she finds that it is, the cliff could be a good place to practice. c. betty could check in town to see if there are any group tours that include supervised cliff diving, instead of diving alone. d. betty could do some research about the area and see if it is a common cliff for diving. if she finds that it is safe, she could then plan another trip with a group of fellow divers to practice at the cliff.

It is actually B.

It isnt perfectly safe to swim around and make sure the water is deep enough.  There can be dangerous wildlife. currents, etc. Its not *perfectly* safe as the claim says.

    however, coronary heart disease , or chd, is actually a result of coronary artery disease, or cad, said edward a. fisher, m.d., ph.d., m.p.h., an american heart association volunteer who is the leon h. charney professor of cardiovascular medicine and also of the marc and ruti bell vascular biology and disease program at the nyu school of medicine.

  with coronary artery disease, plaque first grows within the walls of the coronary arteries until the blood flow to the heart’s muscle is limited. view an illustration of coronary arteries. this is also called ischemia. it may be chronic, narrowing of the coronary artery over time and limiting of the blood supply to part of the muscle. or it can be acute, resulting from a sudden rupture of a plaque and formation of a thrombus or blood clot.

    the traditional risk factors for coronary artery disease are high ldl cholesterol, low hdl cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to fisher. obesity may also be a risk factor.

    “coronary artery disease begins in childhood, so that by the teenage years, there is evidence that plaques that will stay with us for life are formed in most people,” said fisher, who is former editor of the american heart association journal, atvb. “preventive measures instituted early are thought to have greater lifetime benefits. healthy lifestyles will delay the progression of cad, and there is hope that cad can be regressed before it causes chd.”

  living a healthy lifestyle that incorporates good nutrition, weight management and getting plenty of physical activity can play a big role in avoiding cad.

    “coronary artery disease is preventable,” agreed johnny lee, m.d., president of new york heart associates, and an american heart association volunteer. “typical warning signs are chest pain, shortness of breath, palpitations and even fatigue.” if you feel any of these symptoms, don’t delay — call 9-1-1.
