Organ transplants - to donate or not

When the family of a young trucker who died donated his organs to help others, it changed the lives of complete strangers. But can this approach to life be expanded? It's a difficult question to answer, as Liu Zhihua reports from Beijing.

Serious health problems, such as heart or kidney or liver failure, cancer, blindness, or Parkinson's disease affect millions of people around the world, altering the quality of life and putting a major burden on family members and society.

In some cases, an organ transplant may be the only treatment or lifeline available - for those who have access to the procedure. But, even then, there is such high demand for organs that many people can die before they qualify for a suitable organ.
