Shadowboxing rounds are solo episodes, where I, Life-Sparring host Fabian Gruber share “what’s On and Poppin” in my life, what current books provide “Food for Thought,” and what else is going on. No interviews, just a bit of solo rambling and occasionally some bad singing.

In this round of Life-Sparring Shadowboxing: truly awful singing and an attempt to explain it, a first review of the Oura Ring health monitor and reviews of Laura Huang’s book “Edge” and the late Clayton M. Christensen’s book “Competing Against Luck.”
