I’m more referring to when a random person experiences a random craving for something they’ve had before.
Does that generally point to something you’ve had before that unknowingly satisfied a deficiency and which your body tacitly took note of?
I notice it sometimes, like
Beef = i “need” a burger (I’m a skinny dude, beef is not a common staple for me)
Fruit: i need juice or actual berries in yogurt for a smoothie or parfait
Makes sense from an evolutionary standpoint; “I’m thirsty. I don’t crave water. I get dehydrated and die” vs “I’m thirsty. I get water. I don’t die and have babies with Bob” - the person who had a craving passes on their genes
