Being made of wood in an era before protective sealants, the bridges themselves needed to be protected from the elements.
• Most frogs lay their eggs in the water; that way, when the tadpoles hatch they are already in their element. The red-eyed tree frog, however, protects its eggs from aquatic predators by attaching its eggs to the underside of leaves that hang out over a body of water. Once the eggs hatch, the tadpoles fall into the water.

• In ancient Rome, it was widely believed that holding in gas could cause a person to catch a disease or become poisoned. This was such a concern to public health that Emperor Claudius went so far as to pass a law making it legal to fart at banquets.
• Have you ever known someone who keeps making the same error over and over again despite being corrected? The next time you run into this person, you'll know what to call him or her: a mumpsimus.
