Most people who get the flu will have mild illness, will not need medical care or antiviral drugs, and will recover in less than two weeks. Some people, however, are more likely to get flu complications that can result in hospitalization and sometimes death. Pneumonia, bronchitis, sinus infections and ear infections are examples of flu-related complications. The flu also can make chronic health problems worse. For example, people with asthma may experience asthma attacks while they have the flu, and people with chronic congestive heart failure may experience a worsening of this condition triggered by flu. List below are the groups of people who are more likely to get serious flu-related complications if they get sick with influenza.
While traditional psychologists specializing in close relationships have focused on relationship dysfunction, positive psychology argues that relationship health is not merely the absence of relationship dysfunction.  Healthy relationships are built on a foundation of secure attachment and are maintained with love and purposeful positive relationship behaviors. Additionally, healthy relationships can be made to "flourish." Positive psychologists are exploring what makes existing relationships flourish and what skills can be taught to partners to enhance their existing and future personal relationships. A social skills approach posits that individuals differ in their degree of communication skill, which has implications for their relationships. Relationships in which partners possess and enact relevant communication skills are more satisfying and stable than relationships in which partners lack appropriate communication skills.
