HOUSE star Hugh Laurie has found a downside to playing a top doctor on TV - the medical information he's bombarded with in the script has left him unable to retain information. The British actor felt sure he'd pick up valuable lifesaving tips when he took on the role of grumpy DR GREGORY HOUSE, but instead he has been left with memory loss. He explains, "With the quantity of stuff I have to do day in and day out, you have to develop a pretty capacious short-term memory, and I'm afraid one's long-term memory suffers as a result. "So every interesting medical snippet or philosophical perception is gone 24 hours later. "It's actually affected my ability to read. I can't read a novel now. I have to go back four pages to remind myself that the novel's set in the 18th century... I only advance by about a half-page a day."
