That said, how are animals different? I think one big thing is, they do not understand time. Time of day, yes. They have routines. But they don't know how old they are. They don't know how long ago the ice storm came or how old their babies are (but they do know who they are). They all die. But if they die at 20 years old or 1 years old, I don't think it matters to them. They don't wish for longer lives, they just have that instinct that us humans have, to survive- they never really "want" to die, but they all do. They don't know when it was that a dog got in the herd and killed one of their own, they just know that they have an association that they are terrified of dogs. Animals don't know how or why, they don't, they cannot think outside their lot in life. They know the things they need to do (but don't know they know them, if that makes sense), they have the skills for their own little world, they start with the minimum and have the capacity to learn within that set lot in life. But nothing else beyond it. But they are very sensitive, small changes can totally change the hormone environment in their body. A smell, a certain person's presence.. all by association or instinct.
