Trying to find a particular lesson

Hello, heroes!  I know this is a very long shot, bit I figure it's worth a try.  When I first joined the community, I went and read like all the blog posts.  I do not recall which one it was in, but there was a link to a very simple module about first aid.  It was like a text base game where you had to save this person from dying.  You have to choose the correct first aid in the correct order or the person dies.  If that sounds familiar to anyone, can you let me know where to find it?  I've been scouring the blog posts for a week, but I just can't find it.
