Each week Mairead likes to talk to someone all about their obsession in life, and this week was a particularly impressive one - Claire Walsh is obsessed with the sea and free diving.
Free diving is the sport of holding your breath underwater, so like scuba diving but without an oxygen tank. Her deepest dive is 59 meters, and she can hold her breath for a whopping 5 minutes 59 seconds, the same length as Queen's Bohemian Rhapsody!
Claire isn't doing depth training at the moment, but she meditates and practices mindfulness for the mental aspect of free diving. She also swims in the sea daily which helps her find calmness in discomfort.
