Overheard in a medical practice waiting room as a doctor is walking his patient out:
Doctor: "It is very important to get out of the house and stay social, even if it's just going to the shops. It doesn't have to be an organized activity, although those do often have the highest cognitive benefit."
Elderly Patient: "Well, I'm a very Christian woman, doctor, the Lord is my guide and if he feels I should do something then he tells me. He directs my life, I'm just along for the ride"
Doctor: "In that case I think you're going to be easier to treat than I'd thought!"
