Get a new body. Just walk up your desired body and then grab the back of their neck. After that, you squeeze it until they become unresponsive. You cut down the back starting at the nape of the neck and all the way to the butt crack and stop. You pull out their spine and crawl in. You may need to relocate some of their organs for you too fit. Afterwards, have a friend stitch up the back of your new body. In about 2 days, the nerves should connect and you should fees as if you where the body you took over. Congratulations, you’ve just become the proud owner of someone else’s body! Enjoy your time, for you can do this indefinitely to become immortal.
