I know that the Altmer can live quite a while. I've heard it's around 1000 if they don't succumb to a sickness or violence. However, what of the other elf races? Orsimer,Bosmer,Dunmer?

Also, my Altmer is currently 205 years old, in a human perspective, what would he labeled as?(you know, child, teen, elder, advlt etc.)

Thanks for the input in advance.

I'm also curious about mer lifespan. I haven't found any references other than the biography of Barenziah (she lives through the whole Third Era, it seems), and some other examples that feel quite wrong to me, like Yagrum Bagarn. As the TES universe is, immortal or long-living mer feel... off.

Have a look in http://www.gamesas.com/topic/1301354-race-life-spans/page__p__19608474__ http://www.gamesas.com/topic/1282582-lifespan-of-the-sentient-species/page__p__19388698 http://www.gamesas.com/topic/1273698-life-expectancy/page__p__19282776 http://www.gamesas.com/topic/1239460-average-lifespan-of-tes-races/page__p__18806418 http://www.gamesas.com/topic/1169662-typical-life-span-of-the-races/, there's hundreds asking similar questions and they might help.

Alsohttp://www.gamesas.com/topic/829898-altmer-aging-system/ seems to look into your second question. Search Function all the way.

That was very helpful, thanks a lot.
