You know that you’re doing something right when you catch Oprah’s eye. Last week, the influential arbiter of fully lived lives gave a shout-out to Kingston’s O+ Festival on Life Lift: the Oprah Blog.

In the words of its organizers, it’s about “bartering the art of medicine for the medicine of art.”
