### Afraid to cough

John was a clerk in a small drugstore but he was not much of a salesman. He could never find the item the customer wanted.

Bob, the owner, had about enough and warned John that the next sale he missed would be his last.

Just then a man came in coughing and he ask John for their best cough syrup.

Try as he might John could not find the cough syrup. Remembering Bob's warning he sold the man a box of Ex-Lax and told him to take it all at once.

The customer did as John said and then walked outside and leaned against a lamp post.

Bob had seen the whole thing and came over to ask John what had transpired.

"He wanted something for his cough but I couldn't find the cough syrup. I substituted Ex-Lax and told him to take it all at once" John explained.

"Ex-Lax won't cure a cough!" Bob shouted angrily.

"Sure it will" John said, pointing at the man leaning on the lamp post.

"Just look at him. He's afraid to cough!"

### Smoking and heart disease

In 1961, statistical evidence linking heavy smoking with heart disease was reported in the Journal of the American Medical Association. Drs. Daniel J Nathan and Dr. David M. Spain had studed 3,000 men. They found that for smokers of over 40 cigarettes daily and aged under 51 years, their chance of having coronary heart disease almost doubled. Further, among those studied that had coronary heart disease, 57% of heavy smokers suffered heart attacks, as compared to only 31% of light smokers. The doctors said it remained an "open question" whether the statistics were proof that heavy smoking was a cause of hardening of coronary arteries. Only a four-sentence article on page 3 appeared in the New York Times.«*
