For the many seniors who live in some form of retirement home or assisted living residence, getting outside is a special and yet rare and limited event: A stroll in the garden, a walk or wheel around the block, sitting on a bench in the sun, perhaps a drive. All are welcome distractions, I'm sure, but they can't compare to the mobility and social engagement that many seniors once enjoyed.
In Denmark, where almost every senior remembers what it feels like to ride a bike, the loss of that ability is more than a loss of exercise; it also removes one's ability to experience and enjoy the world beyond a very limited local environment.
This explains the extraordinary success of Cycling Without Age (cyclingwithoutage.org), a social movement that enlists volunteer "pilots" to take older adults for a free ride in a three-wheeled bicycle-rickshaw hybrid, or "trishaw".
Cycling Without Age was founded in Copenhagen in 2012 to help residents of a local nursing home get back a bicycle and feel the wind rush through their hair.
