Sure, I'll start.
We mentioned earlier that one of the challenges is the plethora of stuff out there and not knowing whether it's worthwhile or not. I know lots of people who've used certain apps for physical fitness. They use them for a few weeks and then get bored with them. That doesn't really work.
How do you get things that really work, and what do you need to go along with that? I think we've heard lots of good suggestions on that as well.
Some of the barriers have also been mentioned this morning, that it's very hard to drill down and really get some of this knowledge and support and technology to those who are most at risk of chronic disease, because they're living in poverty or other things. I think that's another big challenge, how to share this knowledge and capacity more equitably among all Canadians.
