This occurs when you don’t have anything on your mind. You've stopped worrying about every thing around you. you forget you left the washing out, you don’t bother to put a heater on because you can stay warm under the bed covers. There is no doctor to visit Catch up with a friend for coffee? Can wait for another day. Check the letter box? Nobody writes any more. Some vacuuming? You swept under the table the day before. Lunch? Sit up and watch TV with a sandwich and a fruit. Water? There’s always a bottle at hand on your bedside.
