On the way to South Africa we had a day in London. One of the things we did while there was to visit the Wellcome Collection - a museum dedicated to exhibitions about health. Henry Wellcome was a medical entrepreneur and his estate provided funding to start this collection and it's mission to deal with Health care ideas.and It had a large collection of medical devices including some 19th century artificial limbs.
There was also a collection called Play Well. It featured exibitions of things to enduce children and adults to play constructively. which has good health implications. With various subtleties such as a dolls' house that was open on both sides to encourage children to work together. Also Legos and larger collections of objects to place in play areas that would encourage experimental construction.
I remember as a child I loved setting up and modifying my elaborate electric train layout and also playing with erector sets to build elaborate structures;.
