QUOTE : One interesting study has recently found that lack of activity i even associated with personality change, and by this I mean change for the worse. Overall, lower levels of physical activity were associated with changes in three of the 'Big Five' factors of personality (these are openness, conscientiousness, extraversion, agreeableness and neuroticisim, easy to remember as OCEAN). Lower level of physical activity were associated with declines in openness, extraversion and agreeableness, suggesting a 'detrimental' pattern of long-term personality change. Eve minimal levels of activity were found to have moderating effect on personality change. Those individuals who were the most inactive were the ones most likely to show these negatives personality changes.
