I am a Viking at heart, an old Norse seafarer
nice tell me more about the vikings 
They were very skilled in advanced sailing and navigation skills
Thew were also known as berzerkers they would take drugs, and wont feel pain during battle
I did not know that.  Also, they reached the north east coast of North America 
Thats awesome , one of my favorite animes is berserker the main character is based on a viking 
They certainly spread trade throughout that part of the world and their own demographic
They were brutal warriors
