-
for Scola's medical records.
-
Tom Scola may have done a lot of bad in his life,
-
but he did at least one good thing.
-
He was a bone marrow donor.
-
When a patient receives a bone marrow transplant,
-
the sick bone marrow cells are destroyed and replaced
-
by the healthy bone marrow cells of the donor.
-
And since bone marrow produces blood cells in the body,
-
the transplant recipient begins producing blood cells
-
with DNA identical to the donor.
-
The problem is, it's hard to find a match,
-
but the odds are better
