How old is Dora originally?

Excuse me, but I'm a bit confused about the paragraph you've mentioned. It doesn't seem to contain any direct reference to a person named Dora or her age. Could you please provide more context or rephrase the question in a way that includes details about Dora's origin and the source of the information you're seeking? Alternatively, if you're asking about a fictional character or a person mentioned in a specific document, I'd be happy to help you phrase the question more accurately once I have more information.
