I think simpler is the right word as others have put it. I was born in 1941 (showing my age here!) and grew up in Withington so most of my childhood memories lie with post-war Britain. Significant things I remember: the death of King George VI, the end of rationing, and the outdoor bog. I think we pine for things to be the way they were when we were younger because we were carefree and had less responsibility. I suppose as we get older our worldly experience increases. I moved abroad when I was 20 for pastures anew, living most of my life since in New Zealand.
I find it quite interesting when I hear young people saying they'd want to live in a previous era. Forgive my condescension, but if you can live without things like your cellphone, long-distance air travel, internet, telly? (can only speak for myself here, we never had one growing up), and your modern medicine, then I wish you luck! Not trying to make the 50's and 60's sound like the middle ages, but they certainly were simpler times. I'm 73 and I absolutely love the internet, and I'd like to think I've become acquainted with using a cellphone after 7 years (was just about forced by my daughter to start using one mind, after I had a fall). My grandson started university this year. If needs any information for his essays and whatnot, all he needs to do is put in a few key-words on a website and he instantly has thousands of relevant articles at his disposal. I don't think he's had to set foot in his university library yet, it's absolutely flabbergasting.
Excuse my digressions. Would I go back to the 'old days'? Definitely not. The past I feel, is exactly that. Also, how would I have rekindled my love for City here on the other side of the world without satellite television and the internet! Certainly beats a telegram from dad in 68 saying we'd won the first division a week or so after we'd actually won it!
