Interesting. Seems the Norse were quite the adventurers and not afraid of the unknown.
Well some must have been. But some legends are not necessarily true.
Truth? Now that is a subject for the age.
In the “information age” it appears that the pursuit of the Truth has been lost.
Life as portrayed on TV and the Web, are largely devoid of “the Truth”. Science has become fake, like fake news. When things don’t make sense, “follow the money”. There you will find the reason for the lies.
