Intro
Your brain is a thinking organ that learns and grows by interacting with 
the world through perception and action. Mental stimulation improves brain 
function and actually protects against cognitive decline, as does physical 
exercise.
The human brain is able to continually adapt and rewire itself. Even in old 
age, it can grow new neurons. Severe mental decline is usually caused by 
disease, whereas most age-related losses in memory or motor skills simply 
result from inactivity and a lack of mental exercise and stimulation. In 
other words, use it or lose it.
