This week we are having an in depth look at smart watches. We've been wearing the Apple watch and the latest android offering for a week to see if they are life changing! One thing which could be life changing are exo-skeletons and we meet an ex-serviceman who is paralysed from chest down who can walk again using one. And we look at what tech can do to help predict earthquakes and to prevent the damage which comes with them.
