In China, almost all public parks and neighborhoods offer outdoors free gym equipment, which have led to a continuously active lifestyle, especially for the elderly.
One of the most striking things about the cities of Beijing, Shanghai, and Qingdao, that I noticed in the past 7 months that I've lived in China are the number of the elderly - even in their 70's and 80's - who are active: strolling, playing chess on a street corner, and most often, using the
free exercise equipment in the neighborhood parks.
China's parks and neighborhoods always have two features: a playground and a number of self-sustaining exercise equipment - typically treadmills, elliptical machines, and a few stretching chairs.
These equipment are a brilliant free way to promote health and an active outdoors community. What I've noticed is that often, the elderly also start forming other social activities - night-time dancing, group tae-chi exercises, chatting while eating snacks - around these spaces.
Seeing the elderly enjoying these spaces speaks directly to the vibrancy of a city to me.
