ELI5: Explain Like I'm 5

Clive Wearing

Clive Wearing is a man who got very sick. He caught a virus that hurt his brain. His brain could not remember what was happening in the moment and could only keep memories for a few minutes. That means he couldn't remember anything for very long. He can't even remember what his family looks like or how to do everyday things. He still remembers music from before he got sick and he loves to sing, but other than that he doesn't remember anything else.
