Introduction

An estimated 100 million retirees, mostly women, hit down to the local park with a portable sound system and proceed to bust some moves. The dancing aunties are taking up a lot of space, so much space that the Beijing central government had to step in and build more public squares for them. China's National Health Commission expects the cohort of people aged 60 and over to rise from 280 million right now to more than 400 million by 2035. What happens when 400 million people need assistance getting into and out of the shower each day? When they can no longer climb the stairs or cook and clean for themselves.
