Keep in mind this is a much smaller scale than any bigger society but there are some Belgian communes for example that use time as a metric. For example: I work x amount of time doing stuff for you, like working in your garden, and you then owe me x amount of time to do something for me. Basically everyone trades their time to meet the needs of the commune.
Considering I was suffering from bronchitis for three weeks and I will soon go on a 2 week holiday to what is basically a vertical only island I am starting to wonder why I ever registered to run a marathon in october lol. But I will keep training and inshallah
