Once you accede to the "precautionary principle", you are lost.
There is no end to the regulation that may be imposed "just in case this or that happens".
And, you will discover a whole new raft of legislation as a direct result of your dalliance with socialised medicine... Obamacare.
Over here, the National Health Service is used as a stick with which to beat the populace. The logic goes like this ... "You can't smoke/drink/eat/whatever, because everyone has to pay for the treatment that you will receive." It's the perfect excuse for restrictions on just about all worthwhile activities. I expect it to be more assiduously applied to sportsmen and such-like, as the budgetary constraints become more apparent. I mean, Britain is just as bankrupt as the US.
Enjoy.
