I've used Phosphatidylserine for decades, recommend it to my friends. After about three days very difficult tasks become easy. Piracetam is incredible stuff for certain personality types if you are male. Myers-Briggs NT or SF personalities use both halves of the brain. Males lose the cooperation of the hemispheres at puberty. I'm NT. Some piracetam got me back all the talents I developed in childhood. I started writing poetry, could recall the names of kids in my first grade class, planning and executing plans became much easier... I just moved, am assembling my desk in the new digs, going to re-read this book to make sure I'm not missing some part of life.
