It is a pkm. The infantry trains for 10-12 mile hikes, the Knights by comparison were bums, who had squires to do all the lifting, and broke horse's backs, surfing on everyone else's work and efforts.
Knights Were the Most Honorable and Chivalrous of Men
The Myth: Knights were brave and courteous warriors. They stood up for the innocent and killed the wicked.
The Truth: Most knights were young men with high testosterone levels, and when they were not fighting in a war, they were wreaking havoc on the local population. In fact, towards the end of the 11th century, local lords used these knights to fight over land, which resulted in the slaughtering of entire villages. When the church grew tired of these conflicts, they commanded the First Crusade to compel these young men towards the Middle East, where they massacred the entire population of Jerusalem.
Its safe to say, Knights were a silver spoon class of Imbeciles.
