Alien races would have overcome ageing in much the same way we have. During the first millenia it was considered fortunate for man to reach 35 years
of age. Now look at us. We can expect that the more artificial their enviroment the longer they will live, but that doesnt mean they are immortal.
Gravity and high 'G's are easier to endure given a lower body weight, but that isn't the point here
Research on early (Pre Cambrian) lifeforms identified the workings of evolution. Put simply, upon the rapid change of enviroment an adult organism
will not change or adapt to the new conditions. However - if it can survive and reproduce, its offspring while still in gestation will change to meet
the new conditions with far greater chance of survival when born. This is the basic agent of Evolution and we can apply this to any creature.
We can even consider ourselves if we were to inhabit an 'off world' colony or multi generation (zero G) spaceship. As previously stated the negative
effects are muscle wastage, bone decalcification, intra-cranial pressure and associated problems including pressure on the optic nerve and pressure
distortion of eyeball shape.
To adapt to this change of enviroment we can expect the next generation to have a far slimmer and diminished body. A larger head and larger eyes,
first as a response to elevated intra-cranial pressure. Second, to increase the optic nerve thickness and resist ICP distortion of the eyeball. Add a
few more generations and there is your archetypical alien which once was human.
As for todays fanciful notions of Aliens 'joining' human culture that is about as backward as Monkeys expecting us to climb back into the trees with
them. Its a retrograde evolutionary step and isn't going to happen. LGM's might well be able to perform adequately at 1G but we would never rate
their chances working down a coal mine or helping out with a Lumberjack. But that is Human life and the physical nature of it cannot be ignored any
less than the repeated descriptions of 'Greys' or LGM's being rationally described as having bodies shaped by zero G.
