It’s a great superpower. In my 30s I got to experience my 20s (I pretty much wasted those years working) and had a bunch of early/mid 20 friends. I didn’t stand out. Everyone thought I was their age, but I had the brain of a 30++ year old so men couldn’t take advantage of me. It was awesome. Had I done that in my actual 20s, I would’ve made a lot of mistakes…
