@lauranne I'm going to give you a break because your frontal cortex is still developing and you're in the zone where you think your smarter than you actually are. Give it another 3 or 4 years and your brain will be better developed and see things with a different perspective.
@Gibbon are you sure 4 years will help? After all, you reached your 70s without knowing what the frontal cortex does, so I don't think age necessarily helps!
