An official survey has been published comparing life in 1971 with life in 2011.  It concentrates on "lifestyle" issues and highlights things like the decrease in the number of marriages, the decrease in smoking, the increase in drinking and the increase in people living on their own.  But it got me thinking - what is the most significant change between living then and now?  There's central heating and double glazing for instance - commonplace now but very rare in ordinary houses back then. Then there's television - just three channels then, and hundreds now. Supermarket shopping was still a relatively new experience back then, and mobile 'phones unheard of.  But the most fundamental change in my opinion is the advent of the home computer and everything that has developed from it - the internet, online shopping, video streaming and the like.  What do you think?
