I dive into this topic today with the author of a new book about how heat makes us stronger.  Good news for this summer-loving podcast host!  My Guest: Bill Gifford has written about health, performance, and longevity for more than 20 years. He is coauthor of the #1 NYT bestseller Outlive, with Dr. Peter Attia, and author of Hotwired: How the Hidden Power of Heat Makes Us Stronger. He lives with his family in Salt Lake City, Utah.
