A patient's family gathered to hear what the specialists had to say. "Things don't look good. The only chance is a brain transplant. This is an experimental procedure. It might work, but the bad news is that brains are very expensive, and you will have to pay the cost yourselves."

"Well, how much does a brain cost?" asked the relatives.

"For a male brain, $500,000. For a female brain, $200,000."

Some of the younger male relatives tried to looked shocked, but all the men nodded because they thought they understood. A few actually smirked. But the patient's daughter was unsatisfied and asked, "Why the difference in price betweem male and female brains?"

"A standard pricing practice." said the head of the team. "Women's brains have to be marked down because they have been used."
