Of all the failed technologies that litter the onward march of science - steam carriages zeppelins armoured trains - none has been so catastrophic to prosperity as the last century's attempt to generate electricity from nuclear fission.

I realised how paranoid and guarded and not trusting - walled-in - I had become. Not consciously so but just this armour that I kind of have protective armour. It's not for my friends or family but for being.outside in the world always on guard.

I don't want to clip on the armour every morning. I've seen some politicians do this and they get a bit mangled and bitter. I just refuse to do that. I refuse to be angry or bitter or complain and I remain open. I may sometimes be a bit too open but I'm not going to change that one bit.
