“…Extraversion has also been found to predict the amount of physical activity in a 4-week longitudinal study (de Bruijn et al, 2009). In addition, extroverts have been found to have higher motivation to engage in leisure activities (Lin et al, 2007), and express higher positive emotions derived from leisure participations than introverts (Hills & Argyle, 1998).
