Did You Know?

As living conditions improve and the science of medicine advances, the longevity of the average American has increased greatly, from about 45 years in 1900 to over 75 years today. But the most impressive human longevity is nothing compared to the 400-year lifespan of an ocean clam found near Iceland, or the 5,000-year lifespan of the bristlecone pine, a tree found in the western U.S. We may use longevity to talk not only about actual lives but also of the useful "life" of things: the life of your car's tires or the shingles on your roof, for example.
