Being in the C-suite is a high-pressure job with long hours, board responsibilities, and intense scrutiny. But what is it like to be a top executive when you’re off the clock?

Fortune’s series, The Good Life, shows how up-and-coming leaders spend their time and money outside of work.

Today, we meet Dr. Megan Rossi, the 36-year-old award-winning gut health scientist, TV regular, and best-selling author better known as The Gut Health Doctor.

Raised in Cairns, Australia by a single mum, Rossi’s career path was shaped early on by family loss: her grandmother’s battle with bowel cancer during her final year of university in 2009.

“I watched her go through chemotherapy and surgery, feeling frustrated with the gut for what it had done to her,” Rossi recalls to Fortune. “Not long after, I sat in a lecture on the early warning signs of bowel cancer and couldn’t help but wonder if we spoke more openly about gut health, could her story have ended differently? That question has stayed with me ever since.”
