Depression is some sort of mood disorder in which you may feel sad, helplessness, worried or a loss of interest in life. Now new research suggests that 44 is the age at which we are most vulnerable to depression. 10 % of people have depression at some time in their lives. Depression happens most often in people between the ages of 24 and 44 years.
From the BBC article:
Data analysis on two million people from 80 countries found a remarkably consistent pattern around the world. The risk of depression was lowest in younger and older people, with the middle-aged years associated with the highest risk for both men and women. Andy Bell, of the Sainsbury Centre for Mental Health, said mental health problems were extremely common - but he stressed they could occur at any time in life.
