Oh dear, here we go again. Privatising the NHS and selling it to the Americans.
Yes, I've considered what happens when we leave the EU. We'll be a reasonably large economy, capable of and free to trade with, and strike trade desls with, whoever we please and that wants to do deals with us. We aren't a small country subject to a hostile takeover, we're a nation capable of living in the big bad world without needing Nanny Brussels running things for us.
That seems to be the difference between pro-Brexit and pro-EU .... the latter don't seem have any faith in our ability to be able to cope perfectly well outside the EU. I do. It's not just the US that's keen on a trade deal either - so are plenty of others, big and small. Anyone, in fact, where it's of mutual benefit.
As for thermal shock, I said my 'ool was "coldish", not near freezing. Yeah, people die of cardiac arrest from thermal shock but in very cold water, and the resesrch I've seen suggests the best way to avoid that is to keep your head above water until acclimatised - which is good advice for a post-Brexit UK too. Even jumping into a relatively warm pool feels cold, when your body temp is higher .... for a few seconds. Then you realise it wasn't as cold as you thought, and that while jumping is unplesant for about 3 seconds, then you remember you're in Florida an an unheated pool is about 85 degrees, and the water is lovely, not the cold you feared. Come on in, it's lovely in here.
