First of all, the proposition that fat people are white is true or false, which cannot be confirmed. Maybe the landlord just drew a conclusion based on a few special cases around him, and did not make a statistical summary of objective phenomena, but this is only an intuitive inference. Then assuming that the landlord's proposition is true, then fat people and white skin are related. Why is this? There may be the following reasons: 1. Fat people eat more and have better nutrition, while well-nourished people generally have smoother and whiter skin. Fat people seldom exercise, that is to say, they don't directly bask in the sun, so they are not easy to get tanned. 3. There is a certain correlation between genes controlling obesity and fair skin. Of course, whether fat people are all white or not requires a lot of examples to make statistics to draw a conclusion.
