For a long time, many of us have wondered whether we’d ever be able to achieve immortality. Films, TV shows, and books often feature such plots; in Harry Potter, Voldemort struggles to obtain the Philosopher’s stone, which will provide eternal life. And in the 2005 film The Skeleton Key, a former slave couple successfully uses hoodoo several times to transfer their consciousness into younger bodies through to the present day.This month, a new film called Self/Less will premiere, and it’ll be based on a similar premise. But could it ever actually be possible to transfer our consciousness into other people’s bodies?
