In ancient Norse, there were warriors known as berserks, who fought with extreme strength, using only their rage in battle. Now, many people use the word berserk when someone gets extremely infuriated. What happened to me was hard to describe. I was extremely angry at this one guy, and I flew into some sort of trance where I couldn't feel any pain and I started laughing uncontrollably (The people who heard me told me after I had calmed down that it sounded extremely scary and psychotic). Then, when I tried to attack the person who made me angry, it took 5 adults (at least twice my weight) to hold me down, when usually my best friend can do it alone, and he is slightly shorter than me. Just so you know, I am only 15, 14 at that time, and I am VERY scrawny. I barely have any muscles on me at all. What do you guys think, is it something to do with my ancestry (I am swiss, coming from an area that was conquered by the Norse long ago)? or is it some sort of ability that I have (that's not the first time that happened)?
