My 15-year-old mind was sharp as a whistle. Or do I remember correctly?

My 15-year-old mind was sharp as a whistle. My 15-year-old mind could see all possibilities at once. Imagine a solution to every problem. Look into the eyes of a girl and see all the universes.

Omega 3s prop up my 50-year-old mind, but I dispute the studies that say mind falters with age. Half those possibilities are realizations in this brain. Imagined solutions, pfft, I store proven ones. A wife and family and the known universe fills my memories.
