Expect the government to take a big interest in your health. For starters, if your couch-potato kids are starting to resemble the couch, expect a letter from the school warning you of that fact. Because the government is so politically correct, of course words like "fat" or "obese" will not be used. Neither will "lardy", "gut-bucket", or "wobble-bottom".
Also, expect civil servants to decide who gets what life-saving drugs, based on how much they cost, and where you live (the Scots get drugs the English do not, because the power base of the ruling Labour party is in Scotland).
I loathe insurance companies, but given that government workers fall into two camps - morons and crooks - and are unresponsive to public pressure (unlike private insurance companies) - I think I'll be sticking with them.
