Measuring Pollution In Humans 423
CHaN_316 writes "Scientists have begun measuring pollutants in our body and the results sound like a chemical clean-up site. They've found things such as flame retardants, chemicals derived from DDTs, mercury, uranium, cotinine, and many more. The concern is a lot of this stuff is ending up in mother's milk.

And, of course, this is one of the primary examples in intro statistics courses to explain why you need to know more than just such a sound-bite claim.

Life expectancy at ages 20 and up haven't changed all that much, despite all the medical advances. There has been a small improvement in advanced countries, mostly due to the elimination of some infectious diseases. OTOH, in some parts of the world, life expectancy past childhood has decreased in the past few decades.
My wife, whose specialy in grad school was medical economics & statistics, likes to invite people to take a stroll through graveyards around here (New England) and note the ages at death. She actually did this for a class, and found that for people who lived past 50, the mean age of death was the same 100, 200 and 300 years ago as it is today. The difference is that there are now very few child graves.
