"Dangerous" refers to situations or actions that can cause harm or injury. This can include activities like extreme sports, where participants face physical risks, or environments such as construction sites, where safety hazards are present. Understanding the level of danger helps individuals make informed decisions about their safety. Risky behavior often involves taking chances that could lead to negative outcomes. For example, driving without a seatbelt or engaging in drug use can be considered risky due to the potential for accidents or health issues. Recognizing these risks is essential for promoting safety and well-being in daily life.
