 I think one of the major barriers is mutual understanding on the part of health care professionals and telcos. Telcos have been doing pilots for years with various results, but until we can combine them into an evidence-based framework that clinicians will actually use then it won't be as effective as it could be. And we need to get to scale. Well, if you look at the world today, there are about 400 million people that don't have access to affordable health care and there's two key words there, access as in reach coverage and affordable. I think telcos can make a huge difference in that. We can provide the coverage and we can also make the solutions cheaper as well. I'm very pleased that we're working together with the ITU, the World Health Organization in this new Be Healthy, Be Mobile initiative because we have many different stakeholders. They're not all governmental but some of them are. We have different regulators, telco regulators, health ministries. We need as many partners as we can if we're going to crack this. We need to get to scale in order to solve the world's health care problems. I would hope they would take away that technology is exciting and drones and lasers and AI is great but just with a simple phone call, simple coverage, a phone, voice and text you can do amazing things to educate people and to improve their lives.
