Would Cadence live for a long time?

I wonder about this because that would mean Shining Armor would age and die before her unless unicorns too have long life-spans (though so far only Earth ponies have shown to age like Granny Smith).

It's hard to say if Cadence is immortal. We don't even know if Luna is immortal or not. I would say have to say no for Cadence being immortal. Mostly due to the fact she may not marry anyone due to that. So I think she will age. Still we don't really know.

I think it is a good thing that Princess Cadence can fly. She wouldn't live long at all if she couldn't, what with Shining Armor chucking her off of balconies all the time!

She doesn't give the same vibe as the sisters. She seems fully grown. And at least when Lauren was involved, Luna was yet to reach her full growth. "Luna Eclipsed" basically hinted towards this with her increase in height compared to her first appearance. 

 

This is just another one of the many subjects that make alicorns so darn confusing.
