Playtime For Grandma

"A new outdoor playground in Berlin's Preussen Park is the first of its kind in Germany. Instead of catering to screaming tiny tots and children with boundless energy, the space is strictly for adults. The equipment, in fact, is designed for people at least 1.5 meters (5 feet) tall -- children can use it only with adult supervision. The idea is to encourage seniors to exercise."

"Eight graffiti-resistant machines made of robust stainless steel are laid out on a layer of soft bark under a canopy of trees. It looks as if someone has taken a gym and placed it in the middle of a forest."
