A computerised 'guardian angel' may soon show how you will look in 50 years - based on the cigarettes you smoke, how much you exercise and the type of food you eat.
A government delegation will fly to the US next month to examine the computer program for possible use in Hong Kong hospitals.
The Massachusetts Institute of Technology is developing the Guardian Angel, a program which records all medical data on every citizen, from womb to grave.
Each person receives a number at birth and records are kept of health histories and dietary habits.
Researchers say the program will be able to show young smokers colour images of how they will look after 20 years of smoking between zero and 20 cigarettes a day.
It will also outline how they would look after years of drugs or fatty food.
Hong Kong is already working on a 'Health Information Super Highway' with computer-based medical records similar to Guardian Angel.
