Have you seen ads for these #games on your phone where they claim to estimate you #brain#age based on how well you do? They seem to imply that if your brain age is high/old then you are feeble and if it is low/young then you are sharp/smart.
What is IQ? Intelligence quotient. Mental age / physical age. The higher your mental age the higher your #IQ.
It seems like they have it backwards. An older brain is smarter.
