It was just an ill thought out off the cuff remark by one MP, which has been blown out of proportion by the media and all sorts of others with personal agendas have jumped on the bandwagon. I think the comment was in regards to some recent hacking but has since been manipulated to refer to wars, terrorist attacks, prolonged blackouts etc..etc..
I think most people could quite comfortably survive on what they have in their cupboards for three days as many shop for a week anyway. I have always believed it is simply being responsible to have supplies of dry goods and non perishables in case of a prolonged power outage but I’ve never bothered with a wind up radio. I did look at rechargeable power packs to maintain a TV or radio for a few days but at 800 quid decided I’d just have to bite the bullet and talk to the wife instead.
It did remind me of the power outages during the miners strike, when I was in my teens. I sat in the evening and built plastic kits by candle light.
