Humans? Well not all humans live that long

No the usual lifetime in mass effect is 150

Quarians, turians and humans: 120-150 years

Asari: can get over 1000

Krogans: also 1000 (unknown if that's the limit?)

Salarians: 40

Volus: 20

Vorcha: 40

Batarians: i think 85 or higher

Drell: like humans?

Proteans: 1000+

I find it odd that humans live to 150 os we are a short lived racecompared to the othersexcept for salarains

Well think about it this way back in the 18 century, people didn't even got over 50 years, in the 19 century they nearly got 80 and now 20 century people can get 90 to over 100 years old. What do you think will happen another century? So it could be realistic if you take it from my standpoint.

Shadow Freddy, Vorcha live for 20 years

Oops yeah 20

As far as I can tell volus could live to 85 ish, Drell are about the same, Elcor are about 700

Im not sure by Volus. Anyway do we know how old Prothens can get? Because by my knowledge we don't know.

No protheans are unknown for how long they live could be immortal or reproduce like asari but it’s unknown only prothean we know is Javik and didn’t learn much about that stuff from him
