User: What factors do countries/laws take into account when they're determining when someone is legally an adult?
Assistant: This can vary based on the individual country or culture.  Some countries use a very young age, such as age 12 years, and others use age 18 years, and some countries have a variable age (such as age 16 years in the UK).  The factors that most countries typically consider include one's mental capacity, educational level, ability to work, family obligations, and rights and responsibilities in society.
