Man receives genetically modified pig heart.

[Catherine]

The man was dying anyhow, but the pig was fine. It is because he was dying that the man agreed to such a risky procedure.
It is not really a free choice when you think you have no choice.

There are much better directions we could go with heart research. Sadly we will keep trying this over and over.
It is like animal testing.  Even though it doesn't work  we won't stop doing it.
