Central heating. I remember ice on the insides of windows and one open fire to heat the whole house!
Double glazing - to keep noise out and heat in.
Supermarkets selling everything, much as the demise of the High Street and independent shops is a shame. I have tried to support them and still use our local butcher, but goods cost more and going from shop to shop with heavy bags becomes harder the older I get.
The internet and wi-fi. How many of us had sets of encyclopaedias? Just think how quickly that information became outdated. I love surfing and researching on line, checking goods, buying things, booking holidays and keeping in touch via email, Skype etc. Being able to contact people from almost anywhere. (A double edged sword, that one!) It's incredible.
Modern cars with comfortable seats and power assisted steering.
Planes and airports expanding. Flights to everywhere. The world is our oyster.
I know a lot of the above aren't good for our green credentials. With progress there are often downsides. However, life has become so different in the last 60 years. The rate of change has been incredible.
