IN THE BLOOD
At the age of 60, John underwent surgery to reroute blood around blocked vessels in his heart. Since then, he has limited his fat intake and stuck to an exercise program. Still, today he is meeting with his doctor to talk about a new medication that would break up the fatty deposits re-forming in his heart's vessels.
Down the hall, 6-year-old Lila is seeing her doctor today, too. Her vessels are also clogged with fatty deposits, which means she is dangerously close to a heart attack, even at her young age. Both of these patients suffer from a genetic disease that affects a substance transported in blood. What is that disease? And why did it affect them at such different ages? As you read this chapter, look for clues to the identity of this genetic disease and the research that explains it. Then, solve the mystery.
Never Stop Exploring Your World.
