>>> you can drink non-alcoholic wine or beer and not notice any difference can't you
Find me a non-alcoholic wine that's anywhere near as good as a decent claret or a fine Rioja and I might be tempted to try it. It's irrelevant anyway though, as I know that you can't. (Similarly, I've yet to come across any non-alcoholic beers that can match a chocolate stout, a Belgian wheat beer, a quality Czech lager or a hoppy real ale).
Yes, consuming alcohol (and other forms of taking drugs into one's body, whether legal or illegal) comes with risks but so does motor sport, mountain climbing, pot-holing, sailing, playing rugby or even simply fixing the TV aerial on one's roof or doing a bit of DIY. Life's full of risks and, hopefully, always will be. They're there for the taking and largely what makes life worth living.
