It can. The appearance of your avatar can change as often as you want in Second Life. Lots of people who want to roleplay being pregnant change their appearance to look pregnant. Your avatar appearance is basically defined by two things: Your body "shape" and your "skin". In this case, as you progress in your pretend pregnancy, you could change your "shape" to make your body bigger in all the right places, and keep changing it as you grow. You could also change your "skin" to give the visual appearance of change in the color and look of your skin.

I am not perfectly clear on what you are asking but I will do my best. If you were a companion of the Doctors then you would likely face death every day, endanger loved ones, and grow old while the Doctor stays young.
The Doctor, who soon became his companion for the movie, did not know he had two hearts and therefore he died on the operating table. Well, almost died. If a Time Lord dies, then he does not regenerate. However, He was as close to death as one could be.
