Not all of our cells are replaced as you describe. Some cells in the brain, heart, and eyes last throughout our lifetimes. I'm not making any particular claim that our identity as minds hinges on these three types of cells (though such a case for the brain cells seems, prima facie, like a possible good direction), but if you are going to make claims about what our identity as minds does not hinge on, you should take more care to get the facts straight. ref1: http://www.thenakedscientists.com/HTML/content/latest-questions/question/2961/ http://www.thenakedscientists.com/HTML/content/latest-questi... ref2: http://www.usatoday.com/tech/columnist/aprilholladay/2007-03-30-cell-lifetime_N.htm http://www.usatoday.com/tech/columnist/aprilholladay/2007-03...
