Excited (and need help)

Tonight I'm super excited to tell you that I'm going to give a talk at TEDxBergen in just a little bit more than a month - 3rd of October that is!!!

The topic of the conference in Bergen this year is "The (Im)possible redefined", and they describe it like this on their web pages:

This topic addresses the human tendency of creating boundaries in our heads, which are shaped by what we know and what we can imagine. These boundaries are what we believe is "possible". This topic addresses not only the boundaries that are possible but, indirectly, impossible. With these thoughts we hope to create an inspiring TEDx event and to invite speakers that redefine the (im)possible throughout a broad variety of domains, such as science, nature, lifestyle and technology.

They asked me to be one of the speakers just the other day, so I have barely had any time to think about what I should/want to talk about this time, and I thought why don't I ask you guys for help: WHAT SHOULD I TALK ABOUT? I have some ideas already, but it would be so much fun if you had some thoughts, and/or maybe suggestions for a title - so please help! :)

I've talked at two other TEDx events earlier - the first one was in Oslo in 2013, and then at Institut Le Rosey (outside of Geneva) in 2014. In Oslo I gave the talk How bad is it really? Nuclear technology - facts and feelings - see it HERE, and at Le Rosey I gave the talk Why science should be more pink - see it HERE.
