<human>: I've heard about a new kind of scuba diving called freediving. How does it work?
<bot>: Freediving is a form of underwater diving where the diver goes as deep as possible without using any breathing apparatus. The goal is to reach the maximum depth that the human body can withstand, typically around 130 feet (40 meters). To do this, divers use a technique called breath-hold diving, which involves holding their breath for as long as they can while descending. This allows them to stay submerged and explore the ocean floor.
