A team at Rovaniemi Polytechnic studied one group of 40 people, aged between 65 and 81, and found there were significant improvements in balance, speed and co-ordination after just three months of larking about on the climbing frames and play equipment.
Given that more than a third of elderly people say they are nervous moving about because of a fear of falling, these are statistics that interest people working with senior citizens.
Well, I think this is pretty cool. But one has to wonder about the playground brawls that might ensue.
"Get out of the way, Grandma, that's MY swing!"
Finnish playground manufacturer Lappset is already on board, creating "3 generational play" equipment, suitable for kids, their parents, AND their grandparents.
Many fear that corpulent, inactive parents will simply fall off the swings and see-saws and sue the council, or aggressive teens and 20-somethings will drive the toddlers from the park and vandalise the equipment.
Indeed, the Finnish manufacturer has found that it has to make its equipment extra sturdy for the British because of the levels of vandalism.
It seems it simply does not occur to Finnish youth to destroy things that are built for their pleasure.
There are also cultural barriers. In tests on groups from different countries, the Germans were found to be fondest of having the generations play together.
The French seemed to prefer to control children.I think it all sounds like fun. But getting the world to agree...that might be a different story.
