And finally.

A patient's family is gathered to hear what the specialists have 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?" the relatives ask.

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

Some of the younger male relatives try to look shocked, but all the men nod in understanding, and a few actually smirk. Then the patient's daughter asks, "Why the difference in price between male brains and female brains?"

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