No Proof Lifestyle Changes Can Prevent Mental Decline

I think most people hope to prevent cognitive decline as we age, so I chose this article.
In this article,researchers has failed to find strong evidence that lifestyle changes - like diet , exercise and stimulating the brain can prevent cognitive decline in older people.
But, exercise, diet and cognitive stimulation showed some positive effects.
So I think healthy lifestyle is important.

What do you think about this?
