To say that I learned infinite things would be false, but I learned a great many things.
So many that it will take a long while to process it all.
I learned, for example, at the site of Charles' H.Q. before the Battle of Wagram, now the Wagram museum, that soldiers experienced such profound dysentery so ergularly that it altered their pelvic structure -- added material to the, erm, end. Found regularly in skeletons excavated from battlefields.
