Bonnie: This book is a cultural and scientific exploration of our human relationship with water and swimming. We've been talking a lot about survival and community and competition and flow and all these reasons why we do it, and well-being. Before all of this, I would've said survival definitely is the most vital reason for swimming. Now I keep thinking about survival in all these different ways in these times. You and I were chatting about this before, just that we are in this moment of great uncertainty. We need time to recalibrate and be with our thoughts to understand what it is that we're thinking. Right now, getting in the water is one of the best mental health things that we can do. It's so restorative. I know that a lot of people these days aren't able to get into pools because most public pools are closed. I've been getting into San Francisco Bay and doing open-water swimming. I was just thinking about how the other day I ran into a doctor friend of mine. She had never been an open-water swimmer. Of course, I'm watching all these people adapt and putting on wetsuits and figuring out inflatable buoys and things to get out there and feel safe. We were walking up from the beach and she said, "I just feel so much better now. This has been a week." Just the moment of stepping into the water and seeing the expansiveness and experiencing the connection to the water and the world, I think that is so important. We're wired to respond to that. Again, the science just resoundingly supports how we find so much benefit in immersion.
