Andrew, you seem to place a great deal of trust and faith in polls & analysis carried out by civil servants, academics, and independent polling companies.
I wonder if your cats eat Whiskers (9 out of 10 prefer it), and your wife (or partner) uses the anti wrinkle cream that 47 of the 61 people polled say actually makes them look younger.
I also doubt you have 2.4 children
I'm sure that the people behind these things believe the results achieved, otherwise there would be no point to them.
PS, apparently in the next 50 years or so my house could be under 6ft of water (global warming) but up to now I have refrained from building an Ark
