Is there a way to keep track of the things you "like" on Facebook?

I know that the minifeed records when you "like" the page for a band, activity etc. but nothing ever shows up on your page if you "like" someone's pictures, wallpost or comments and I've had it happen before where you leave the "liked" post not realizing that you had accidentally "liked" it. Maybe it's just me being paranoid, but I'm always afraid of awkwardly "liking" a post from someone I don't know very well, especially if it was from a long time ago. Does anyone know if there's a record of your Facebook activity somewhere or if there's someway to check?
