My Sim keeps jogging, even though i never told him to.

There is a mod to stop the autonomous jogging. An in game solution to have a break from this sims compulsive behaviour is to make a club, put the offending behaviour as forbidden and start a gathering. Club gathering affect the autonomy to, as Hollidays also do. Another thing that affect the autonomy is having some skill at something, like having some point in fitness will make more likely that a Sim exercise. Wims are another thing that has an effect on autonomy.
