 It's a good reminder for me, and I hope for you, too. This message is brought to you by the U.S. Air Force. If you think dangerous blood clots can't happen to you, think again. Up to 900,000 men, women, and children are affected by blood clots each year, and about 100,000 die from them. Blood clots don't discriminate. You or a loved one could be at risk right now. The good news is blood clots can be prevented.
