Two long short stories 'Eternal M' and 'Big Al' dealing with brain downloading. In 'Eternal M' a Mafia Don finds a professor that he believes is his ticket to immortality. The professor has no idea what's in store for him. In 'Big Al' a multimillionaire used car salesman is enticed to join a group of very cerebral virtual people needing the money for their existence. A very bad idea.
