This can be filed under "old news" for some of you, but for others it may be helpful information. Hans Rosling, who developed Gapminder, has a new presentation linking economic growth to health over 200 years. (HT to Mark Perry because his blog is where I ran into it first. Since then I've seen it many times, many blogs.) When you talk about measures of progress in the early part of your macro classes, you might want to offer this as a way of explaining how economic progress affects in social progress. It also offers an entre for discussion of coincidence, correlation and causation. Regardless of how or even if you use this presentation, imagine a not too distant future when you can do something like this in your classroom.
