 My name is Ferrena Metic, I'm the Director of the Centre on Aging at the University of Manitoba. I'm also the Site Principal Investigator in Manitoba for the Canadian Longitudinal Study on Aging. I think CLSA is unique in many ways. One of them is it's very large. We're trying to involve a lot of Canadians, so 50,000 people. We are trying to follow them up, which is really unique over at least 20 years. So we can really look at aging, not just at what they're like at one time point. And it's a national study and I think that's really important because Canada is diverse when we think about from Newfoundland to Vancouver Island, so it represents that diversity in Canada. And it's really rich in terms of the data that we're collecting. It's going anywhere from the biomarkers right up into retirement issues. So I think it's phenomenal in terms of its richness. Well my interests are in how the social and physical environment that people live in relates to their aging and how it makes them age well or not. So the social environment can be in terms of social supports, but it can also be at a broader scale in terms of where they live. So for example, do they feel safe in their community, in their neighbourhood, where they live. And then from the physical environment side, are there supports in that environment in terms of the physical structure, for example, sidewalks? Are they well maintained? Are they walking paths? Is there housing? And what we know is that these factors are all important in people's lives as they get older. Healthcare utilization is measured in a number of ways in CLSA. It asks, for example, whether people were hospitalised. We know that is a big issue, whether they use emergency rooms. And so there are medication uses, another big area. And all of these questions are really important to ask because we know that older people use healthcare services more. So the question is, what are some of the factors that relate to why they're using healthcare? And so we have a range of questions around healthcare utilization. Healthy aging to me is a very broad concept. It includes physical health, so I think having people be healthy is very important, but that's not the only thing. I think people need to be able to do what they want to do. They need to be socially engaged. It relates to well-being, life satisfaction, having a purpose in life. So very broad. This is truly unique. It's a unique study. It's unique in Canada, it's unique in the world, and being part of that very much in a hands-on way is phenomenal.
