Popping Pills

Last week in the train going to BLR from Mumbai, I saw a coach full of men and women wearing a badge 'lose weight now...'. They were carrying pamphlets that promised to help people lose weight with the help of pills and powders... Ironically most of these people were looking not fit themselves and had a potbelly. Each of them carried a lunch box full of pills of different sizes and colours. And popped a handfull of them after dinner....What's more, I googled their product on the Net and found that their founder died of a overdose of pills mixed with alcohol.. Why would people still continue to buy this stuff?..
