This article's a couple of years old, but I just came across it and, well, as someone who might perhaps fall into the definition of "Grup", I found it interesting. It made me feel "OK" about, at 39, still living a lifestyle reminiscent of my early 20's, while it simultaneously served as yet another reminder of "Gee... I'm almost 40. You mean I'm not supposed to be acting this way anymore?"

Well,I am not acting my age either

It’s about reimagining adulthood as a period defined by promise, rather than compromise.

I like that

Where is it written that there is a dress code or anything that says you have to do or say things at a certain age?
To me it's a simple thing as mind over matter. I lost my mind so it doesn't matter.
