1: The heart is a vital organ present in many animals, its primary focus to pump
blood around the whole body. It is part of the circulartory system, and must be a very strong muscle to be able to transport oxygen all the way around the body quickly. Beef heart and pork heart can be eaten (stir fry it, make some broth etc.), and is said to help with your
sleep.
2: Metaphorically, the word heart means the centre of a persons thoughts and emotions, especially
love, compassion, and loyalty.
Examples 1:
1a:
Person 1: Damn, my heart feels like it's burning.
Person 2: Maybe take some indigestion tablets, it should help.
1b:
P1: Damn, I couldn't
sleep at all for four days. I've just been drinking 50 monsters whilst rubbing one out for 6 hours and feeling
ass at 13:00.
P2: Maybe have some pork heart, apparently it helps you
sleep.
Example 2:
My heart broke when my favourite character died.
