Unfortunately some people are still very conservative and lack this ability to think critically and do independent research. They still think that the doctors are the authorities for health issues and that everything the doctors say are correct and everything others say are wrong.
Here in Hong Kong we have exactly this issue. It is really a shame since we claim to have received some of the best education in the world. People still retain this attitude of reliance on others, because they believe that with money they can buy/have everything.
It is actually a really irritating phenomenon.
