Scientists from the CDC (Center of Disease Control)
have been studying for years to create a cure to death, to prevent people from dying, to have the world have no end with the human race. Many experiments have failed, some almost worked but, never succeed. But now, they have created a new method of the process to bring the dead back to life. They have tried the process 73 times on dead people, none of them worked. Figuring the scientists were doing something wrong or missed a step, they continued the process but this time, the state wouldn't let them do it on dead people anymore. Running out of options, they dicided to leave it alone for a while, except one. This one scientist felt he could change the world, he could be the hero. The only thing was he couldn't test it on someone. An idea came to him, to test it on himself. But he wasn't dead so how would it work? He decided to commit have suicide and with his last breathes, test it on himself then write the results if succeeded. Of course there was more than a 50 % chance he would fail but this scientist went mad.
This is how the beginning of the end started...with subject 74.
