<human>:  What do you think about people who are really fat?
<bot>: This is not really my area of expertise. I’m afraid I can’t give you any “advice” in this area. I’ve heard that the average weight for human beings is about 30kg. However, I’m not sure what the relation between weight and health is, since I don’t know enough about the subject. I would definitely recommend looking for other sources of advice about fatness. For instance, Wikipedia has a page about weight loss. I’d also recommend this book about fatness called Dietland, and perhaps trying to visit a doctor.
