Your cardiovascular system (with the heart organ) and your brain. If you fail to have either one working you will die. You can live without some organs but never the heart or brain. That is why we have organ donations for most organs but not the brain. The brain cannot as yet, be fully and properly transplanted. If you are declared brain dead the nervous system will be gone and cannot keep your body functioning without artificial means. If your heart fails, oxygen will fail to reach the body and the body dies. If you get a good, viable heart transplant you could live for many years as long as your body does not reject it. Therefore they are the most priceless parts of our bodies.

Given all the things that President Obama could say, and speaking as a father, I would say that Barack Obama would most likely say that his wife Michelle and his two daughters would be his most priceless possession. Priceless without a doubt, maybe not a possession, but definitely a gift!
