Puzzle for December 3, 2008

The first human heart transplant happened today in 1967 in Cape Town, South Africa. The patient lived for 18 days before dying from complications to pneumonia.

By 1977 patients were living up to 5 years after a transplant. Nowadays 50% of patients live at least 10 years.
