Via the Daily Mail:
Internet blog sites, conspiracy theorists and forums are awash with rumours as to what those mystery scars on the president's head are from.Whether you buy into this one or not, one fact is true. There is very little known about this man's background.
In pictures, Obama appears to have a long scar which goes up the side of his head and over his crown.
Some conspiracy theorists claim they are scars that you would see on someone who has had brain surgery.
But without medical records (along with his school records and birth certificate) no one seems to be able to provide an answer as to the cause of the mystery scars.
Ben Hart, a blogger for Escape The Tyranny a website which presents itself as a Social Network & Forum For Conservatives, said: 'Obama's almost done with his first term, and we still know almost nothing about the background of the President of the United States.
'Whatever happened to create that scar, it was clearly something serious. Was it a brain operation? Has it affected his thinking?
'No one is allowed to see his birth certificate. He is just one big mystery man, which adds intrigue to what that huge scar is all about.'
