well, ain't nothing like the discovery of x-rays to make a fella reevaluate the whole notion of seein' right through things, i tell ya. before these rays came into the picture, pre-inception and all, we'd disavow any notion of lookin' inside without opening up first. but with these here x-rays, doctors don't need to be reticent no more, hesitant to make a move without knowin' what's beneath the surface. at the briefings, they learned how to reconfigure their approach, making the world of medicine a sight more hopeful, i reckon.
