I'm not sure either is unambiguous like that... Might I suggest something like:

“Do you get tired if you read too much?”
Sam nodded.
“It’s the same," Kare continued. "I know what I want to do, and my mind does it.”


Edited to say: I must be insane since both Inter and Aber feel otherwise, but the second version implies to me that Sam is speaking -- at least that he's speaking the second bit. Does it depend on the context?
