Some of the most expensive sports to play include equestrian, formula racing, sailing, ice hockey, and golf. High costs come from equipment, training, travel, and maintenance.
The hardest sport in the world is often considered to be boxing due to its intense physical demands, mental toughness, endurance, and high injury risk.
Hockey games typically have three periods, each lasting 20 minutes of play time. If the game is tied after regulation, overtime or a shootout may follow depending on the league rules.
