Can 'Doctor Who' live forever?
The Guardian has this story about the plans to remove the 'rule' about regenerating only 12 times. It states that in 'The Sarah Jane Adventures' that the issue will be addressed.
This could 'in theory' make the Doctor immortal. I'm not sure how I feel about that or how accurate the story is so I'll leave that for the future.
Here is the link to the story on 'The Guardian':
I found this additional story from 'Den of Geek' about this so I thought I'd add it to this story as well.
I'm sure we'll hear more about this as things continue.
