The 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 costs 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 look shocked, but all the men nodded in understanding, and a few actually smirked. Then the patient's daughter asked, "Why the difference in price between male brains and female brains?"

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