Very interesting, very gory. thanks for posting whirlibird.
Gotta wonder what it would take to have your own personal storage of blood if SHTF.
My med kit currently has enough bandages to plug a serious wound, pull shrapnel out and stitch up once or twice, and hardcore dose of antibiotics. But internal injury is beyond me, scarey **** what a 7.62×39 or a .308 will do.
Never be afraid to do the righteous thing, nothing righteous is ever easy.
