At 70 years old, Mark Sommer trains six days a week and lives with the drive of a man half his age. In this episode, Mark talks about his blue-collar roots, the lessons he learned from his father and grandfather, his years as an iron worker in New York City, and how discipline, faith, and discomfort shaped his life. From ocean swims to keto living, this one’s packed with wisdom and grit. Thanks for listening to Time Squared, we'll talk soon.
