Which half ?
An eighty-year-old man was having an annual physical. As the doctor was listening to his heart with the stethoscope, he began muttering, "Oh oh!"
The man asked the doctor, "What`s the problem?"
"Well," said the doc, "you have a serious heart murmur. Do you smoke?"
"No," replied the man.
"Do you drink in excess?"
"No." replied the man.
"Do you have a sex life?"
"Yes, I do!"
"Well," said the doc, "I`m afraid with this heart murmur, you`ll have to give up half your sex life."
Looking perplexed, the old man said, "Which half - the looking or the thinking?"
