They seem to know.

After my mother passed, I found an old essay talking about when her father (my grandfather) passed. She wrote that the last time we saw him, he seemed to know something was up, and then died that night.

My other grandfather figured it out after a blood test determined that he only had a few days left. His kids (including my dad) weren't going to tell him. He was 102 and otherwise healthy. Then, he wheeled himself across the nursing home into the meeting with the social worker, and announced the funeral home, church, and cemetery that his arrangements were with. He had such a big smile too. He "won" and couldn't ask for anything more.
