1 Your lochia is still bright red four days after your baby's birth. 2  Your lochia has a foul smell or you come down with fever or chills, which can be a sign of a postpartum infection. 3  You have abnormally heavy bleeding (saturating a sanitary pad in an hour or having blood clots bigger than a golf ball).
A great white shark, for example, would be able to detect a single drop of blood in an Olympic-size pool. Most sharks can detect blood and animal odors from many miles away. Another amazing thing about a shark's sense of smell is that it's directional. The twin nasal cavities act something like your two ears: Smell coming from the left of the shark will arrive at the left cavity just before it arrives at the right cavity. In this way, a shark can figure out where a smell is coming from and head in that direction. Sharks also have a very acute sense of hearing.
