I think we both made a mistake. You told that we don't know how much Misa's original life span was. I told that how much ever Misa had, Gelus's life span would be added. But on the contrary (which I realized now) Misa's life span is already over... if you remember the assassin who almost killed Misa. So, Misa's original life span was over and so only Gelus's life span remain. but after 2x eye deals, only 1/4 of Gelus's life span remain. But if Rem have her life span to Misa, (still), Misa would have lived longer than Light Yagami.
