FEEDBACK:
This lesson worked very well, although practical reasons forced a few changes. I showed the first part of the PPT with the 3 examples then when we got to the causes of stress I simply brainstormed them on the board. Then we discussed ways to relieve stress and I wrote them up in a different colour. We continued with the people's problem and asked students to suggest advice using "You should... You could... Try to... Why don't you?...", etc.
I abandoned the prompting exercise - my students english is low level so I simply got them to make a dialogue in pairs, practise it, then we read a few examples. I suppose you could play around with the plan to suit your class/classroom.
Thankfully the topic was nowhere near as sensitive as I'd feared and since the results of the study in this weeks article are for 2009 it should be a lesson that will work for a while.
