But! Sometimes stuff really is silly. This one just escapes me- and there is a real significant question it raises - when do we "know" something?
Researchers in the UK have spent a considerable amount of time, effort, and money- to discover that- wearing 50 lbs of steel armor will make you more tired than not wearing it.
In the formal abstract for the research, they state: "How much wearing armour affected Medieval soldiers' locomotor energetics and biomechanics is unknown."
And end up with "Our findings can predict age-associated decline in Medieval soldiers' physical performance, and have potential implications in understanding the outcomes of past European military battles." Translation: old soldiers have a hard time carrying lots of steel, and maybe gasping for breath could have affected their performance."
I have to tell you- I really think "we", as in scholars interested in the field - "knew" that before the treadmill tests.
But there are a growing number of researchers who actually believe that if something is not published in a journal they recognize, then in fact we do NOT know it.
It may seem trivial- but I think it may not be. How do we decide what is in our joint pool of "true" information?
