If I have good reason to believe that someone whose name begins with "Æ" wants very much to split my skull, I will absolutely wear a helmet, but I will also take more useful measures such as having a shield, weapons of my own, and a bunch of pals who have banded together to hold a tactical position that makes it extremely disadvantageous to attack us.
A helmet won't save Svend if he get hits by 2 tons of w@nkpanzer. There's a reason that heavy cavalry charges were so devastating.
I thought Denmark were better than this.
Cool video tho.
