That's a good question.
When you asked about housing's capacity to address the mobility issues that elders may have in terms of adaptation, I was going to say that this is an issue, clearly.
Our communities right now are small, but they're expanding, and they're expanding with a low density. Transportation is an issue for people, especially if they don't have their own vehicles.
Some communities now have community buses. There is transportation so that elders can get to the health services they need or to the grocery store when they need to. However, they are often dependant on their own family members and on the availability of their family members.
I don't know if that responds to your question on mobility issues, but I think it's an issue of urbanization that has not been fully addressed. With the growing chronic issues such as hip problems, walking is clearly not as easy, especially in the winter. They depend a lot on transportation by others, but also on public transportation when available in the community.
