SIR – Be afraid! Be very afraid! On top of the long list of things which are dangerous such as playing conkers, smoking, eating hamburgers etc, it now seems that blowing your nose, having sex or drinking coffee can cause a stroke. Too bad, and whatever next? Should we have warnings stating, ‘Living can cause death?’ Do people get paid for generating scare stories?

Whatever else I may give up, it will not be coffee.
