I think one of the biggest differences a visitor from 1950 would notice is food.<p>The Germans were called &quot;Krauts&quot; in the second world war because they ate Sauerkraut, a then prevalent way to preserve some food with vitamins for the winter.<p>And today you can go into the store in winter, and buy twenty kinds of fresh fruit from all over the world, and twenty more types of vegetables.<p>You don&#x27;t have to stockpile for winter, and don&#x27;t have to change your diet signficantly because fresh stuff is unavailable.<p>We don&#x27;t think of that as a huge technological advancment, but it has a huge impact on the daily life. Likewise the prevalence of washing machines. The availability of public and private transport in a way unimaginable to somebody from 1950.
