This line represents the trend. So let's just keep going backwards. Keep going backwards at the same rate. So something like that. I wanna make sure that it looks at the same, looks like it's the same rate right over here. And you could just try to eyeball it. You could say well see, 20 years ago, 1945, if I were to extend that line backwards, it looks like there were about 52% of the population was smoking.
