If I could just comment, I certainly agree with these figures. The number of chronic conditions we have to live with, of course, does not diminish with age. It increases. For instance, nearly half of people in their eighties have three or more chronic conditions.
But the fact that someone has a chronic health condition does not invalidate their ability to contribute to the workforce, because we can use a number of strategies involving lifestyle, habits, physical activity, nutrition, and so on to cope with these conditions. Molecules—drugs—can also be used to control these conditions, and if the work environment is a contributing factor to these conditions, then we can facilitate some of these lifestyle activities, including, for instance, physical activities.
The other comment I would like to make briefly is that I think the real first look we will have at all of this longitudinally is through the Canadian longitudinal study on aging, which is starting now. For the next 20 years we'll follow individuals between 45 and 85 years of age, including aspects of their health, biology, cognition, attention, and so on, as well as their environment and their work history and how they contribute to work.
I think we will be getting this information very soon and we will make sure this evidence will be brought to your table.
