you should watch it from a more distant angle. that video is real, but probably taken from selscted shots. for sure, it has been used for raising money. however, rather get away from a horror view. it is nothing more than an early heart-lung-machine. besides the dog-head (which has been used only for the demonstration that the machine is partly able to replace heart and lung), the other experiment (dog sucked empty and refilled after death) is for very real, and many times approved by following operations. many others failed, as they have been executed in the late 20s. anyway, the same process happens today and everyday, and those people invilved are probably very happy that heart-lung-machines have been invented once. as i said in my post before, dr gibbon has experimented the same, just with cats. he was only lucky, that the patents of brychonenko haven't made it's way to overseas. about the discussion of dead, which the video is not about, the aspects are difficult. for sure, it can't be simplified to an amount of body left. and absolutely not can it be related to the ability of procreation. procreation as an argument for bein alive is for a strange one. i might say, it is a very strange one - and has been abused in the dark ages of last century a lot!
