Lots of valleys in Wales so I'm fine. I can also make a tower of sheep and then stand on them.

stay in my house and go swimming in the new public pool that just opened up

living in Norfolk, I would say I'm ******. I guess run for higher ground :P

Would opt to die as resources would be next to none, unless you're into sushi, but good luck living on that for months on end. Depends, if its just the UK then aid would eventually arrive, or so you hope, else you would eventually be left with nothing and starve.
