yeah thats what I thought as well? 😕

nah Superman can't be immortal...cuz he's not mortal...nor a man...he will live on until he gets killed, get sick, or the sun burns out which ever comes first.

I think it depends on the structure of the kryptonian cell, how it functions and how much solar energy it can store. Logically, a man who is genetically immune to everything on earth (except to kryptonite radiation) should not age. Senescence, at least as we know it, should not exist for Superman.

BTW aging is not universal. A number of complex species such as lobsters, rockfishes, some tortoises, etc. do not appear to age. Therefore, aging is not a prerequisite to life. Aging is neither inevitable nor universal.

X-43D I must concer with your rather indept statements.

I doubt Superman ages quickly, and the sun is a very reliable source of energy. Superman will live until someone kills him, or until he runs out of solar energy.

I think of him as Yoda for some reason, in the 900s. Or imortal.

I like to think of Superman as a nuclear reactor. It is well known that Superman can enter a nuclear reactor and exit unharmed. Basically he could always draw energy from the sun and other sources, until the universe runs out of energy (if ever). If that's the case, then his life-span is infinite.

In the Batman/Superman Comics, an older version of Superman goes back in time and fights the younger Superman. The older Superman was stronger due to the fact he had been under a yellow sun for more years yet he looked older. Does this mean superman will be stronger when he's an old man in a nursing home? I don't quite understand the correlation.

maybe..him and Lois also had a kid.

I don't get it. If his cells are indestructable, how in the hell does he ever shave or get a haircut?

As far as I concerned Supes can live as long as DC wants him around.

Hair is dead cells, so they would not be indestructable.

The question should be 'How does he have hair?' seeing as though his cells should be immortal

hair is not a dead cell....there is a follicle in the hair that doesnt die, ever

3975.3 years.......

he'll live until I *picks up his kytonite ray cannon* decides to destroy him....fighting18

The easy answer, pretty damn long.

Until he dies.

Superman prime is immortal, and since that's what DC is pretty much promoting as his future, we can take that as his more or less canon. It was not an else worlds tale. It was an actual future (possible future) for the JLA.

Looks like virtual immortality, these days. Aging at an incredibly slow rate, once he hit adulthood. After the first thousand years, maybe he starts hanging more with Gods from Olympius and Asgard, because all his human friends will be dead.

Well I read someone saying if someone kills him that is not exactly true if he stays under a yellow sun and his body keeps taking in sunlight he will come back to life so he is virtually unkillable.
