Hi Bug, sorry I've been away and not on the forum, but for the future....when explaining to a non-academic audience, I agree with Bilbo, do it as if you're explaining what you're doing to your family or friends...to make it fit with the academic peeps though, throw in some technical phrases and find some simple means of defining them , as if you were teaching it, to show you know your field well but you're matching your audience. And finally for the nerves, Bachs Resuce Remedy is simply amazing! It's a herbal infusion of flowers-type thingy, basically an alcohol extract, but its great for settling
nerves!
