This definition can be contrasted with that proposed by life-span developmental psychologists: Development is a life-long process beginning at conception and ending at death (Honzik, 1984, p. 309). Development is thus extended to include the whole of life.

A cockroach can live for a week without its head. Due to their open circulatory system, and the fact that they breathe through little holes in each of their body segments, they are not dependent on the mouth or head to breathe. The roach only dies because without a mouth, it can't drink water and dies of thirst. A cockroach can hold its breath for 40 minutes, and can even survive being submerged under water for half an hour. They hold their breath often to help regulate their loss of water. Cockroaches can run up to three miles in an hour, which means they can spread germs and bacteria throughout a home very quickly.
