Psychiatry is the medical specialty devoted to the diagnosis, prevention and treatment of mental disorders. These include various maladaptations related to mood, behaviour, cognition, and perceptions. See glossary of psychiatry.
Many psychiatrists and psychologists refuse to entertain the idea that society as a whole may be lacking in sanity. They hold that the problem of mental health in a society is only that of the number of ‘unadjusted’ individuals, and not of a possible unadjustment of the culture itself.
There are two basic kinds of impersonations: those that are publicly supported and those that are not. Examples of the former are an actor playing a part in a play or a small boy playing fireman. Examples of the latter are a healthy housewife complaining of aches and pains or an unemployed carpenter claiming he is Jesus. When persons stubbornly cling to and aggressively proclaim publicly unsupported role definitions, they are called psychotic.

The growth of blue-green algae in our lakes, large ponds, water reservoirs and public waters constitutes a problem for our environment and for our health. These types of algae often result in a deterioration of the water quality and emit a distinctly unpleasant odour. The algae consume a lot of oxygen in the water, leaving little for other animals like fish. They also produce toxins which can cause skin irritations and are suspected to be involved in the occurrence of liver cancer.
