Great concept but its still some way ahead. In many countries, many people have yet to even have access basic healthcare. Africa is a good example where basic healthcare is still largely unavailable. Some of the more developed countries like China still has a long way to improve their healthcare policy for the mass. Some of you who are living in China will understand what i mean. Healthcare is a luxury for many here as its simply too expensive for the average Chinese to see a doctor. A trip to the visit the doctor will easily cost $50 and above and if you compare that with the earning per capita, its way beyong the reach of many. Perhaps the billions of Bill Gates donated can be put to good use.
