Hmmm
I scored 51 with a 69 year old brain on my first try, I had a hard time with the 5 number diagrams. No doubt the brain does lose reaction time as we age. I am sure the score would improve with practice, which sort of destroys the validity of the test
Given the choice I would pick my overall brain at 50 over my brain at 20 every time.
So many ways to measure various talents. I think most of us are savants in something if we ever find that thing.
I can do daily newspaper crosswords without a pencil. Hoopdedoo :)
