What if children designed our cities? Today we speak with play consultant, experience designer and creative strategist Leticia Lozano. Leticia is the Co-founder and Director of MACIA Estudio, an applied research and design studio, and also the head of Playful City at LabCDMX, Mexico City’s civic innovation lab. Leticia speaks with us about the rules adults play by, a child’s first five years and why play-filled moments are the best ones of our lives.
