It really shocked me to know that wearing of scarves has been banned in Jinnah Postgraduate Medical Centre (JPMC) by the administration. How backward can we get? Just when the West is adopting our norms and values, we are dropping them. Haven't these people heard that the western girls now prefer to cover their heads while cooking because science has proved that human hair attracts more germs than any other part of the body. JPMC should reconsider. By banning scarves, they are actually promoting unhygienic practices. -RAFIA RUSTAM, Karachi, via e-mail, March 19.
