My father is 85 yrs old. He does not have any routine and sleeps after eating breakfast and lunch. In the evening too he sometimes sleeps while sitting. I am worried as this may make his mind dull. I want him to be healthy mentally and happy involved in some activity. His only hobby was to read and now he cannot do so because of poor eyesight. What kind of activity should I involve him with. Also can someone please direct me to a good website of healthy vegetarian recipes for people above 80 yrs.
