http://en.wikipedia.org/wiki/Quantum_immortality In summary, this theory suggests that from everyone's own point of view, they'd be immortal..since once you die you lose consciousness, but there will always be an alternate universe where you don't end up dying and continue being conscious. Therefore, there's an alternate universe for every single person where they have kept on living. Imagine, people like Hitler, Elvis, Tupac ( ), Len Bias, Alexander the Great, etc... could still be alive and living in the alternate universe they are living in.
This theory must have really blown your mind since you somehow included Len Bias with the rest of those names.
