response: The emotional aspects of a broken heart is believed to be survival instinct
history: i heard of people dying with a broken heart.. have you heard of that? I have not, though a broken heart can refer to physical pain. ohhhhhhh i didnt know that Emotion pain that is severe can cause physical damage to the heart. how often does that happen? have there been studies done ? I don't know the answer to either question, but the concept of a broken heart spans different cultures and goes back at least 3,000 years. thats understandable
knowledge: The emotional ''pain'' of a broken heart is believed to be part of the survival instinct.
