- Americans say "I am good" instead of "I am fine" to mean they are well. In British English, "I'm fine" is more commonly used to mean well. - "I'm fine" can sometimes imply the person needs help even though they say they are fine. It means they want someone to help get their mind off things. - "Good" refers to a person's character or qualities, while "well" refers more to health and well-being. Saying "I am doing well" is more meaningful when asking about health. - "Good" can simply mean "not bad," while "fine" implies something is excellent or superior.
