Posted By Mark Bywater Andrew, I'm not sure there will be many takers on this but for my own part I like to inject bits of humour now and again. An amusing story with a safety angle, you must know the one about the builder and the bucket of bricks on the gin wheel(?) Or maybe some amusing photos from the web, again related to safety, there's plenty about. It's all about making it interesting even when the message is serious. So look at your own style of presentation and add a few things in that your audience won't necessarily expect...it'll keep 'em awake at least. Regards, Mark
