If you get bitten by a black mamba you die. No exceptions.
There is antivenom for most snakes and to dropkick murphys, you're wrong.
Thats complete bullshit, on animal planet this guy got bit by a black mamba, went to the hospital they said that there was an antivenom for it, but it was not at the hospital. So they put him on this machine, I forgot what it did, it was gave him oxygen or something like that. Anyways, the venom shut down his most of his body, and his kidney's filtered the venom out over a few days.
