An avid simmer is a term used to describe a person who is (or was) totally dedicated to simming. Rather than someone who merely has a passing, avid simmers have a time-consuming interest in simming that may last for a few months before moving on to something else. Avid simmers become involved in simming at many levels for years and work to understand and prefect their game.

Most people can only exist in this state for three to five years before burning out, becoming too stubborn for their own good, or being forced out in a revolution. A few are able to retire gracefully, and some find a niche where they can stay involved in simming on a limited level that best suits them.
