Sleep and Why We Sleep
We spend approximately one-third of our lives sleeping. Given the average life expectancy for U.S. citizens falls between 73 and 79 years old (Singh & Siahpush, 2006), we can expect to spend approximately 25 years of our lives sleeping. Some animals never sleep (e.g., several fish and amphibian species); other animals can go extended periods of time without sleep and without apparent negative consequences (e.g., dolphins); yet some animals (e.g., rats) die after two weeks of sleep deprivation (Siegel, 2008). Why do we devote so much time to sleeping? Is it absolutely essential that we sleep? This section will consider these questions and explore various explanations for why we sleep.

What Is Psychology?
In Greek mythology, Psyche was a mortal woman whose beauty was so great that it rivaled that of the goddess Aphrodite. Aphrodite became so jealous of Psyche that she sent her son, Eros, to make Psyche fall in love with the ugliest man in the world. However, Eros accidentally pricked himself with the tip of his arrow and fell madly in love with Psyche himself. He took Psyche to his palace and showered her with gifts, yet she could never see his face. While visiting Psyche, her sisters roused suspicion in Psyche about her mysterious lover, and eventually, Psyche betrayed Eros’ wishes to remain unseen to her.

How to Boost Your Sleep Quality
It goes without saying that we need to sleep in order to function at optimal levels. Sleeping well improves your appearance, brainpower, memory and other vital body functions. It also reduces your risk of gaining weight, feeling fatigued or developing chronic health conditions. Both adults and children need 6 or more hours of sleep every night for optimal health. However, just because you’re getting the recommended hours of sleep each day does not mean that your body is getting the rest that it needs. A lot of people toss and turn all night, don’t feel like getting out of bed in the morning and drink plenty of coffee to avoid drowsiness during the day. If you’re suffering from such sleep problems, then you need to improve the quality of your sleep. Here are a few top tips on how to boost your sleep quality.

Viral Evolution, Morphology, and Classification
The first organisms that originated about 3.5 billion years ago were prokaryotes that possessed the structures and metabolic processes associated with cells (refer to the Cell Structure chapter). As discussed in the chapter on cell structure, prokaryotic cells are much smaller than eukaryotic cells and inhabit just about every square inch of our planet, from the most inhospitable environments to the surface of the skin. Viruses are much smaller than prokaryotes and much simpler in structure. They must reproduce inside a host cell. Their origin is still a mystery to us, but we do know that they can make us very sick.

Enzymes
A substance that helps a chemical reaction to occur is a catalyst, and the special molecules that catalyze biochemical reactions are called enzymes. Almost all enzymes are proteins, made up of chains of amino acids, and they perform the critical task of lowering the activation energies of chemical reactions inside the cell. Enzymes do this by binding to the reactant molecules, and holding them in such a way as to make the chemical bond-breaking and bond-forming processes take place more readily. It is important to remember that enzymes don’t change the ∆G of a reaction. In other words, they don’t change whether a reaction is exergonic (spontaneous) or endergonic. This is because they don’t change the free energy of the reactants or products. They only reduce the activation energy required to reach the transition state.
