Yes, first I was an adventurer, those were my early years. I'd spend my time clearing every single dungeon and fort I could find, fighting draugr, dragon priests, dragons, skeevers, bandits, afflicted, forsworn and vampires. After some time, I got bored of adventuring and started my new job, guard duty. Some of the guards wonder why I chose being a guard instead of an adventurer. Well, as I became older, I realized that I didn't want my life to end like that. I want to help. Everything was fine, but one time when I was walking along the Solitude Docks, I saw a mage. He looked aggressive, ready to fight. I slowly asked: "Hey, do you need something?". He didn't answer. His hands started to burn and I realized he wasn't up to no good. He blasted me with a huge fireball that flew all the way to the door of The East Empire Company Warehouse and created a dent on the door. I charged at him, but I was too slow. He got out a staff with some faces on the top, and fired a projectile at me. At first nothing happened, but after a few second, I turned into what I'm now, a log. But yes, that is my story, now let me sleep.

^\That's what I think happened in this video. He got a flashback to the guard years of his life, and then it cut back to the log.
