Episode notes

Alex and Jordan—born in South Africa. One stayed. One moved to Brazil. Both countries now lead the world in screen time—over 9 hours daily. Different paths, same exposure. A 25-year experiment with no control group. Will we act before it costs another generation?

And Dr Bilal Zafar summarizes how digital or eHealth has transformed the care of diabetes in The Dispatch. Also includes moments of Erin's curiosity and Shehnoor's well-known forgetfulness.
