your brain become your brain cells. this is why people always say: "Mama knows the best". this is why you can sense what your kids going to say and do. of course you have to learn how to properly use the new brain cells. For myself I found out I am actually smarter than before I have kids. I give myself a goal-learn one new thing every day, to train my new brain cells I got from my kids. now I am in age that usually hard to learn new things But I still learn new tech as fast as my No 1 son( but not sport activity).
