Disney? Uhhhhh.......no. I don't think that's a winning bet. You could give birth to a child 10 years from now, that child could grow up to be the longest living person in history, and Disney will use the story of your child as a new film/character. They'll copyright your child's life, and they'll STILL be around 150 years later to dispute that 150 years in copyright protection is too short.
