Several years ago, some doctors in Canada began 'prescribing' art to their patients, giving them free access to a local museum.

The idea was that by meandering amongst the masterpieces and pondering the paintings, patients could achieve better physical and mental health outcomes.

A new study from the United Kingdom suggests that isn't such a far-fetched prescription after all. The arts really may affect biological hallmarks of aging.

Scientists from University College London (UCL) found that a weekly arts or cultural activity could slow the pace of aging about as much as exercising once a week.

The philosophy that 'art is life' may have some real scientific backing.
