Our program is shared from National Geographic's videos published on March 12, 2015 - Caesar Sant of Winston-Salem, North Carolina, began playing the violin at age two and as a toddler amazed his music teachers with his advanced abilities. But by the age of five, he had suffered three debilitating strokes due to sickle-cell anemia. His third stroke left him unable to walk or play the violin. Now, as he tries to regain his musical abilities, he has a newborn sister who can provide a bone marrow transplant that could be lifesaving and could ensure he'll always be able to play the violin. Visit Caesar's Bone Marrow Foundation page and his GoFundMe page for more information.
