When anyone comments to any article, his/her reaction should be taken in context with the write up not with the author's personal character. Second, elderly people can't write anything wrong, is this an universal law? Few months back a very senior retried Railway Official wrote an article in a reputed newspaper where he criticized the use of CBC coupling in passenger coaches. He literally bashed the Railway Board & railway ministry for installation of CBC coupling in passenger coaches and called this a retrogressive act. After few days, Kanpur accident happened and once again proved that screw coupling causes more casualties during an accident. So, whether that "experienced, retired" official was right? Respect the experience but use you own wisdom too.
