Cleaning became an obsession (使人痴迷的事) with Will Palmer after he had a operation of a
cornea (角膜) transplant. Before the operation, Mr. Palmer was happy to leave the housework to his
wife. However, since he had a cornea transplant, he has become liking to do the dusting and washing up,
and developed the good habit he didn’t have before.
     Mr. Palmer said, "Since having the transplant operation, my vision is almost 20/20. I can now notice
every spot of dust and dirt, and can't help but have a go at cleaning it up. For some reason seeing the
grime(尘垢) gets on my nerves and I have to do something about it. It started as a joke that I must have
been given the cornea of a woman. There's a reason why men don't clean like this and I think it’s because we just don't see the dirt, but I see it everywhere I go."
     Mr. Palmer developed corneal disease Fuchs Dystrophy six years ago. The condition caused the inner surface of the cornea - the thin layer that covers and protects the iris (虹膜) and pupil (瞳孔) that is
responsible for two thirds of the eye's vision - to slowly die. This meant that over time, the sight of Will's
right eye had dropped so much that everything appeared unclear. It was also sensitive to light. Later, Mr.
Palmer got the cornea transplant.
     Scientific studies have suggested that up to a third of organ transplant patients have inherited changes in their personalities, preferences and skills from their donors. Researchers have proposed various theories,
including the idea that memories are stored in organ tissue as well as the brain and can therefore be passed on to transplant patients.
