Where do I get ideas for this column? It’s usually from long hours of reading medical reports, talking to researchers, searching the net and various sources. It’s tedious and tiring. But this week I got lucky. I was having a drink at my favourite watering hole when a friend said to me, “You should write about a problem I know that kills people. It also makes them ill and they don’t realize the cause of their poor health”. He then told me some tragic stories.
