Från Wikipedia artikel om Thor (så i princip komisk versionen):
Like all Asgardians, Thor is incredibly long-lived and relies upon periodic consumption of the Golden Apples of Idunn to sustain his extended lifespan, which to date has lasted many millennia.
Från MCU wiki sidan i ett sidofält finns grundläggande information om Thor (filmversionen). Där ser vi:
Age: Over one thousand years.
Powers and abilities:
[...]Thor trained and skilled in the arts of battle, which he has practiced for thousands of years.[...]
Superhuman Longevity: Thor, like all other Asgardians, is not truly immortal. It is possible to kill an Asgardian and other beings in the Nine Realms. More accurately, Asgardians are extremely long-lived beings. Thor ages at a pace far, far slower than a human, as he is at least 1,000 or more years old; more than likely, like Loki, born shortly before the last great war between the Asgardians and the Frost Giants.
När det gäller Loki :
Age: 1051-1052
Powes and abilities:
Superhuman Longevity: Loki has the capacity to live for thousands of years. Loki was a baby at the end of the last great war between the Asgardians and the Jotuns, over a thousand years ago.
När det gäller Odin :
Age: Thousands of years.
Powers and abilities:
Superhuman Longevity: Odin ages at a rate that is much slower than that of a human being. Even though he is thousands of years old, he still in very good health, greatly belying his appearance. When he died, he was over 5.000 years old if not older.
UPDATE: INNEHÅLLER NY INFORMATION från AVENGERS INFINITY WAR
I Avengers Infinity War , säger Thor själv att han är 1500 år gammal .
(Jag kan inte hitta ett online-transkript för tillfället, men jag tittade på filmen igår, och han sa det tydligt.)
