King Abdullah of Saudi Arabia has a blood clot in his back. He was ill during the Hajj with a ruptured disc in his back, and the clot is related to that. The king is also 86 years old, so it's worth taking a look at what will happen whenever he does pass away. So far, all of the kings have been the sons of Abdul Aziz, the founder of Saudi Arabia. After Abdullah, it will pass to the next generation. I'll post more on this later.
