In the year of his16:36:59 death, Copernicus published his Copernicun system,16:37:04 showing clearly that Ptolemy was wrong and that,16:37:07 in fact, the earth and other planets orbited the16:37:10 sun. Galileo agreed with Copernicus, but was16:37:10 forced by the Inquisition to recant his support of16:37:14 the Copernicun system almost a century after it16:37:18 had been scientifically proven.16:37:2016:37:20 "The benefits of spacer devices over nebulizers in16:37:24 childhood asthma may not be as earth shattering as16:37:27 whether the sun or the earth is the center of the16:37:30 solar system, but it addresses an important issue16:37:32 in one of the commonest childhood disorders of our16:37:35 time. How many of us can honestly say that spacer16:37:37 devices have mainly taken the place of nebulizers16:37:39 in our emergency rooms and in our pediatric wards?16:37:43 For this reason, I think the paper of my pal and16:37:46 his colleagues is immensely important. It shows16:37:49 in an exemplary way what managerial steps need to16:37:52 be taken to adopt scientifically proven research16:37:56 results. For true consensus to occur, much16:37:59 explanation and discussion is needed. Didactic16:38:02 decisions will inevitably result in failure,16:38:05 because colleagues and their views, have not been
