Physical inactivity has become a global epidemic, with this generation of kids being the most inactive in history. The document discusses the rise of physical inactivity due to modern conveniences and the normalization of sedentary behaviors. Data shows countries have become 30-50% less active in just 1-2 generations. This inactivity cycle negatively impacts health, education, earnings potential, and economies. However, creating regular positive experiences with physical activity from ages 7 to 12 can help establish active behaviors that last into adulthood. A united effort is needed across sectors to address this issue and shift perceptions of physical activity from optional to essential.
