I remember one sister taking care of her dying mother (mother not a JW) who lamented that she could not count the time she took care of her, because she felt she was doing a good work and she was upset because she was not getting much field service time in because she was so exhausted being a caretaker and this made her feel guilty. But I suppose the Org considers picking vegetables for the Org more worthwhile than caring for your dying mother.
Funny that these stats show up in the hours preached world wide--picking vegetables is a far stretch from preaching in my book.
