assistant: Sure, there are many obscure and unusual sports played around the world that differ significantly from popular mainstream sports like soccer, basketball, or cricket. These sports can differ in terms of popularity, recognition, and competitiveness, often being more localized and culturally significant to specific regions or communities. Here are a few examples:

1. **Sepak Takraw**: Originating in Southeast Asia, this sport is a cross between volleyball and soccer. The ball is made of rattan or hard plastic, and players use their feet, head, knees, and chest to pass the ball over a high net. It's a competitive sport with professional leagues in countries like Thailand and Malaysia. Despite its regional popularity, it's less globally recognized than sports like soccer or basketball.

2. **Wife Carrying**: Originating in Finland and based on the 19th-century legend "Ronkainen the Robber," this sport involves men carrying their wives (or any woman, not necessarily their own) over an obstacle course. The sport is competitive and has a world championship held in Finland. It's not as recognized or popular as mainstream sports but has a unique cultural significance.

3. **Chess Boxing**: This unusual sport, originating from a French comic book and formalized in the Netherlands, alternates between rounds of chess and boxing. It's a real challenge of both mental and physical prowess. While it has a world league and adheres to a structured rule set, it's far from mainstream in terms of popularity and recognition.

4. **Buzkashi**: This is a Central Asian sport in which horse-mounted players attempt to place a goat or calf carcass in a goal. It's traditionally played by the nomadic tribes and has significant cultural importance. Its competitiveness is high among practitioners, but the sport is relatively unknown outside the region.

5. **Hurling**: An ancient Gaelic Irish sport, hurling is played with a stick (called a hurley) and a ball (sliotar), where players aim to score goals by getting the ball into the opposing team's net. While it's very popular in Ireland and has significant cultural and historical significance, it's not as widely recognized or followed globally.

6. **Underwater Hockey**: Also known as Octopush, this sport was created in the United Kingdom by divers who wanted to stay fit during the winter. It's played under water in a swimming pool, with two teams trying to maneuver a puck into the opposing team's goal. The sport has worldwide competitions but isn't as mainstream or widely recognized as traditional hockey.

7. **Kabaddi**: Originating in India, this sport involves two teams where the objective is for each team's "raider" to tag as many of the opposing team's players as possible and return to their own half of the court all while taking a single breath. It has professional leagues in Asia and is featured in the Asian Games, but it's not as globally recognized as sports like soccer or cricket.

These sports differ from more mainstream sports in several ways. They often have a strong cultural or historical significance in their regions of origin, and they may not be as widely recognized or played globally. The level of competitiveness can vary widely, from friendly community games to national and international competitions. However, they all share the spirit of sportsmanship, skill, and enjoyment found in all sports.

These sports often face challenges in global recognition and professionalism due to their cultural specificity, lack of globalized marketing, and sometimes due to the nature of the sport itself. However, they continue to be important components of local cultures and traditions.

user: which are the most dangerous ones?

assistant: While sports can involve varying degrees of risk, some unconventional sports are considered more dangerous due to their inherent nature and the potential for serious injuries. Here are a few examples of sports that are often regarded as more dangerous:

1. Bull Riding: Bull riding, popular in rodeo events, involves a rider attempting to stay mounted on a bucking bull for as long as possible. The rider's skill and balance are pitted against the strength and unpredictable movements of the bull, making it a highly dangerous sport with a high risk of injury.

2. Cave Diving: Cave diving involves exploring underwater caves and passages. It requires specialized training, equipment, and knowledge due to the complex and challenging conditions. The sport carries inherent risks such as restricted visibility, narrow passages, potential entanglement, and the need to manage gas supplies properly. Without proper training and preparation, it can be extremely dangerous.

3. Big Wave Surfing: Big wave surfing involves riding exceptionally large ocean waves, often in excess of 20 feet (6 meters). It requires a high level of skill, physical fitness, and mental preparedness. The powerful waves, turbulent conditions, and potential for wipeouts pose significant risks to the surfers, including drowning, impact injuries, and being held underwater for extended periods.

4. BASE Jumping: BASE jumping involves parachuting from fixed objects like buildings, antennas, bridges, and cliffs. It is an extremely risky activity due to the low altitude jumps, rapid descent, and the need to quickly deploy the parachute. Accidents can occur due to parachute malfunctions, low-altitude collisions, and misjudgments of landing areas, making it one of the most dangerous sports.

5. Street Luge: Street luge involves riding a specially designed, low-to-the-ground board (luge) down a paved road at high speeds. The lack of protective barriers and the potential for collisions with vehicles or other objects pose significant risks. Riders are prone and close to the ground, making injuries from high-speed crashes more severe.

It's important to note that participation in any sport carries some degree of risk, and safety precautions, proper training, and adherence to rules and regulations are crucial to minimizing the dangers associated with these activities.
