[Harry Potter] Could Voldemort have lived indefinitely if he had just avoided any encounters with Harry?

They say that “Neither can live while the other survives” which implies that one of them will have to kill the other. 

If Voldemort just kept skirting Harry, could he live on indefinitely? If so, would he die of old age?

HP leans towards the idea of prophecies being triggered by the people who believe in them, and that they can be rather vague (Harry vs Neville being chosen). 

It’s *possible* that Voldemort could have lived indefinitely by avoiding Harry-him dying of old age depends on the properties of his body. But it’s *also* possible that the line meant that neither would be able to *live* life while the other exists; unable to truly pursue other interests without the thought of their opponent always in the mind’s horizon. The ambiguity prevents any definitive statements from being made.
