 So the Supertrial is about finding out ways to delay disability and when I say disability it means that delaying the risk of falling over, delaying the risk of entering a rest home and we are testing out a programme of exercise, nutrition and socialisation and see that if we follow this group of older people over two years, can they improve in their health. Oh we have 500 fantastic older people from Fungare, Toranga, Hawak and Invercargo. So we measure their get speed, we measure their functional status, we measure their quality of life, their socialisation. So they have been really enjoying this part of the study. Well from what we hear from older people they really enjoy all the classes. They learn a lot, they gain a lot and I think collectively of all the four groups they really enjoy the socialisation part of those programmes. Why is this matter? Because I think at this stage we don't really look for quantity, we're not looking for years of how long we live but we're looking for quality of life. We want to add more life into the years that we have and to enable older people to continue to thrive until the very old age and this is what the super study aims to do.
