• Between 1981 and 1997 childrens free playtime
  dropped by an estimated 25, and this change
  seems to be driven by increases in the amount of
  time children spend in structured activities.

Millennium Where have we come from, where are we
going? 2001

• we demonstrate why play, and particularly
  active, unstructured, outdoor play, needs to be
  restored in childrens lives
• we suggest the term play, not the terms
  physical activity, exercise, or sports, be
  used to promote movement in young children
