I agree with what Penny & Lars say here. 

Using jargon-type words like salutogenesis does not help us as meta-health professionals to connect with the wider world whom we're aiming to reach with our tools, skills and knowledge. 

We don't need to preach to other health professionals by using words like that in our mission statements. A mission statement needs to speak to the masses, whom we're targeting, which is part of our 'why'. 

Clear & meaningful in wording to all is what is essential here, not to just those who work in science and the top echelons of health. 

We're working from the grassroots upwards - this is where our people are coming from who require our skills and knowledge and these are the people need clear and meaningful wording, which they can identify with. Your average person does not identify with words like salutogenesis. I had to look this up & I'm an educated person. 

Penny makes a good point above, in suggesting we all listen to what Simon Sinek talks about in his talk on 'The Why'. This is the essence of where we need to come from. 

And as such, I like the original statement or the suggested changes by Lars.
