It survived past his birth and for sometime inside him, but it was not alive for 36 years...

Since you're sounding quite pompous, perhaps you need to take a biology course. The so called twin is actually considered a type of tumor, it develops tissue and in very rare cases can even develop organs, but is never actually an organism. Basically it sounds like in this case bits and pieces of foetus developed, even surviving past the birth of the host twin, surviving meaning the tissues developed using the hosts blood stream for nutrients etc. To think there was an actual twin surviving for 36 years inside of another human is stupidity. Where did you go to school?
