Today, the eighteenth of April, is David Tennant's birthday. David is best known to us for playing the tenth incarnation of the Doctor in Doctor Who. He has been playing the Doctor since 2005, but this year is going to be his last year as the Doctor, and then Matt Smith will take over the role next year. David turned 38 today and I would like to take time to wish him a very happy birthday and the best of luck for the future.
