She worked in the intensive care unit, caring for patients and administering countless medications every day. At first she threw away all of the empty bottles, tubes and caps, as everyone did – but soon she decided to save the colourful caps, stoppers and connectors, which were still clean and sterile. Her children used them as toys, sorting by colour and shape, and even made jewellery with them. At the end of her career she had saved over 100,000 pieces of plastic and rubber from the hospital.
