Answer 2

Production Losses :

Drinking alcohol may result in production losses from the following:

1. Reduced workforce size as a consequence of death or premature retirement;

2. Absenteeism from sickness or injury;

3.  Reduced on-the-job productivity from sickness or injury and accidents.

Alcohol misuse may also cause loss of production in the unpaid household sector and in other non-market activities. Although the informal economy is not included in the standard measures of market output (such as GDP or GNP), the losses or production in it caused by alcohol misuse may be significant.

2 Types of Drinking Behavior

Drinking behaviors can be divided usefully into two categories: those that occur in response to a significant disturbance in ECF composition and result in a classic homeostatic response; and those that occur in the absence of such a disturbance, but instead are initiated to prevent the occurrence of such deficits. Each of these types of drinking is associated with distinct neural mechanisms (Grossman 1990, Rolls and Rolls 1982).

2.1 Homeostatic Drinking

The most well-studied aspects of drinking behavior are those initiated in response to significant changes in ECF composition. A large body of work has identified specific types of dipsogenic (i.e., thirst-inducing) sensory signals that are associated with particular disturbances to the composition of the ECF. In humans, the most common form of homeostatic drinking occurs in response to exercise or heat-stress. Pathological causes of homeostatic drinking include severe hemorrhage or conditions associated with severe diarrhea.

2.2 Anticipatory Drinking

Drinking that occurs without a major disturbance to ECF composition requires regulation by regions of the brain concerned with the anticipatory components of motivated behaviors. Two groups of brain regions are particularly concerned with regulating this type of drinking; those involved with controlling arousal state and circadian timing (particularly the circadian clock in the suprachiasmatic nucleus), and those cortical regions concerned with the complex processing of sensory objects and their representation in processes such as reward/aversion, and learning and memory (Watts 2001). In these circumstances, drinking is often closely associated with feeding behavior, both temporally and in quantity (Fig. 1). Food-associated water intake (either as a component of the food itself or as a separate drinking episode) represents the most common route of water entry into the body for humans living in economically developed countries (see also Hunger and Eating, Neural Basis of).
