"Imagine that after a routine medical exam your doctor delivers some devastating news: Since your last checkup your cognitive performance has plummeted.
Your ability to connect with others has eroded. And your memory for everyday events is no longer operating as it once did.
But as it turns out, there is a cure and it won't cost you a penny. The treatment is simple. Would you follow the doctor's advice?
All that's required is that you put away your smartphone."
