Strong Brain^℠

Perfoming basic arithmetic calculations quickly is a real brain-builder! Brain scans taken during sessions of fast arithmetic show large sections of the cerebral cortex really lighting up with the effort. The associated research has shown that this exercise improves memory function, and can even improve the functioning of the prefrontal cortex of people with cognitive impairments. It is recommended that you perform this exercise 2-5 times per week, carrying out 5 or more units (15 equations) of calculation each time.
