This is among the conclusions reached by a recent poll. In total 1,120 employed Americans were asked how they occupy themselves on days they are not at work. According to the poll, older people, the rich, and the well-educated are most apt to spend their spare time doing the things they want to do 'rather than those they have to', Overall, high-salaried people were more active than those with lower incomes. They watched less television and were more likely to engage in social and cultural activities.
