Sure, there are a lot of new concepts of living in this new postmodern era, some examples: - https://en.wikipedia.org/wiki/Freeganism - https://en.wikipedia.org/wiki/Genderqueer - https://en.wikipedia.org/wiki/Job_sharing

There are many more examples of new concepts related to postmodernism. Really related is the concept of 'postmodern society': https://en.wikipedia.org/wiki/Postmodernity#Postmodern_socie... Seriously I dont get the downvotes, but I dont care that much.
