Alright, so I'm a high school student trying out college part of this Co-operative education dual credit program. I'm in this course where I don't understand something. So we had to watch this one hour movie called "Unnatural Causes: in sickness and in wealth", I have a transcript of it, and one of the questions I need to answer, which would be on my exam is asking me "what is the wealth-health gradient" What do you guys think this is? Before this question was introduced, I was given a statement saying that a study revealed that people with less wealth have higher chances of heart disease. Is this pretty much the same thing? what do you think? I'm so stressed, help me out. You guys are my only way Lol!
