13. Never Perform Open Heart Surgery On Yourself
There is a reason why we put our trust in doctors when it comes to things like heart surgery. Not only have they had extensive training and know how to undertake it safely, if we stupidly tired to do it on ourselves, we would most likely be dead before we even reach the heart. So many things can go wrong: extensive blood loss, damage to the heart, you might even puncture a lung - any one of these will result in instant death. Having had his healing ability taken from him, Wolverine realizes that the reason is a mechanical spider thing that has attached itself to his heart. When I say realizes, I actually mean "assumes," because they were being used to help Yashida when we first saw them - he has no proof that they are trying to kill him. But that doesnt stop Wolverine. With his powers taken from him, he decides to cut himself open, fight through the pain, somehow get past his ribcage, avoid damaging the lungs, and rip the spider from his heart using his bare hand. "Ouch" doesnt come close. Considering he had no facts to base his theory upon that the spider was the reason for his fading powers, performing open heart surgery was probably one of the most stupid and reckless things to do in such a situation.
