Answer:
Economists use the term demand to refer to the amount of some good or service consumers are willing and able to purchase at each price. Demand is based on needs and wants—a consumer may be able to differentiate between a need and a want, but from an economist’s perspective they are the same thing. Demand is also based on ability to pay. If you cannot pay for it, you have no effective demand.
What a buyer pays for a unit of the specific good or service is called price. The total number of units purchased at that price is called the quantity demanded. A rise in price of a good or service almost always decreases the quantity demanded of that good or service. Conversely, a fall in price will increase the quantity demanded. When the price of a gallon of gasoline goes up, for example, people look for ways to reduce their consumption by combining several errands, commuting by carpool or mass transit, or taking weekend or vacation trips closer to home. Economists call this inverse relationship between price and quantity demanded the law of demand. The law of demand assumes that all other variables that affect demand (to be explained in the next module) are held constant.

Is higher in winter. Around Christmas time and New Years is generally the highest time for suicides. There are many theories about this such as lack of vitamin D from sunlight and the existential crisis of trying to "act normal" while celebrating selfish materialism with the people you've been told your supposed to love in world that seems to be committing suicide on a global scale... or maybe you got the wrong present and are so self attached to you material possessions that you literally can't live without that cheap plastic thing that was produced purely to make someone, who doesn't care about you or the wellbeing of the world, profit. But it's ok the doctor can give you valium and zoloft so you never have to feel a thing.
