Hi:
Well, we have a youth "culture", that started decades ago with the baby boomers. Youth was idolized, focused as the ideal state of freedom and exploration. Youth tossed old norms out the window into the wind.
Now a retirement "culture" is growing, driven by the same people. The style and way that millions of baby will retire is unwritten. However, this culture is not going to be like the old retirement culture, that is for sure. As people are now gearing down to slower lifestyles, more time for friendship and socialization, and more travel.
Ten years from now people will be writing about the culture. It's forming now and being a part of it is fun.
