Cassandra Trimnell was diagnosed with sickle cell anemia in 1987 when she was just a baby.

She inherited the gene that causes this disease from both of her parents, meaning she has sickle cell type SS. This means she can experience the worst symptoms — including fatigue, extreme joint pain, anemia, and infections — at a higher rate.

"And we also want to live forever, see through walls, and shoot lasers from our eyeballs," the Ukrainian scientist tells me with a totally straight face. "But that's all science-fiction nonsense for now. So in the meantime, we're just making yogurt with an anti-aging protein, and things like that."
