Hi Everyone Mel and I have been searching the net for an article which appeared in New Scientist on February 15th. It was written by Laura Spinney and appears on pages 38-42. We met someone yesterday who read this and according to her the article is about glasses which can "get someone going again if they freeze in a doorway " It sounds too good to be true! Has anyone else read it? New Scientist Vol 153 No 2069 Jean & Mel From the land of kilts and haggis.
