I do not think there are many yuppies left or at least they do not show up with the same hardness that they used to do. Undoubtedly, we can find yubbies, that in these latitudes we could call “pijo-progres”.
What about middle-youthers? Well, definitely, they exist. Young people, but not so much anymore, who do not want to grow up. They stick to their old lifestyle, so they want to continue doing the same things they did when they were 25 years old.
