[Halo] Do Spartans Have an Extended Lifespan?
gpt
The problem with asking about lifespan in the Halo-verse is that aging is constantly being disrupted by cryo-sleep and space transit. So someone might be frozen for three years and not age physically, but how would you classify them? 

With regards to the Spartans, the soldiers were in such high demand that there was never an opportunity to study aging.
