actualy, no. it can live more than 99yr old and its age will go more than 99yr old, because kyliesmum's tamagotchi lived up to 100 and something yrs old. plus, your tamagotchi can only mate with another oldie. it cant mate with something that is younger than it is, like it cant mate with an adult. i have an otokitchi and an ojitchi and i mated them and they have oyajitchi now. when you mate two oldies, there child will be oyajitchi. it will be a baby but when the baby grows, it goes straight to an adult. it does not go through child form, or teenager form. oyajitchi is an adult and he was a 0yr old adult. i know because i have an oyajitchi. your tamagotchi will keep living if you take very good care of it.
