How can I introduce pessimists and optimists in my presentation about stress?

[Correction]

Thanks for your help!

In talking about the symptoms of stress, you need to discuss the interpretation of these symptoms for both sides. Ie a pessimist might feel that the heart palpitations mean they are about to have a heart attack and die, an optimist might feel that these same palpitations are confirmation that their heart is still beating,albeit strangely, and therefore they are well and alive.
