The Lancet recently published an article titled “Subjective wellbeing, health and ageing,” in which the researchers concluded that “The wellbeing of elderly people is an important objective for both economic and health policy.”

In the report, the types of subjective wellbeing were defined.

• Evaluative wellbeing: evaluations of how satisfied people are with their lives
• Hedonic wellbeing: feelings or moods such as happiness, sadness and anger
• Eudemonic wellbeing: judgments about the meaning and purpose of life

I found these definitions to be very interesting, as I can see in myself how varying degrees of satisfaction or happiness affect my moods, ability to work and my overall health.
