There is no sport in which self-control is as important as freediving. Every deep dive is an event that can be described as all or nothing.
Freediving is the most widespread and oldest form of diving. Historically, people have ventured into such ventures in search of food, shells, or to explore submerged objects.
Danish freediver Stig Severinsen broke the existing Guinness record by diving 202 meters in the Cortez Sea holding his breath for 20 minutes.
