Rita, I was interested in your presentation as well. I'm sorry that Patrick wasn't here; I know he has developed some mobile applications as well, although not, I believe, at the same level as what you're looking at. I am aware that some apps already in existence can track your calories and your fitness and all the rest of that.
What have you seen? What is the uptake? How many people are using these apps? How effective are they? What is your research doing to go beyond this stage? Are you looking to coordinate those sorts of things? There are some products out there already. How are you looking to take this development to the next level?
