good question......but with a huge dose of "faux" news, dancing with the stars,the kardashians,justin bieber,J lo,Lilo, Scar Jo and remakes of every box office piece of shit ever filmed, is it possible for a child to "develop properly" here?
they are more than "dense enough" already
there is a wrinkle on below 1G planets/moons and what not
take the extreme case, artificial spin world, you provide all the gravity from spin
downside are cost(large) and risk, a spinning tube failure is likely to be the last 1, no ones walking away from that - though extreme fail safes might make the casualty rate less than 100
but someone thought of a wrinkle, using spin on a world that isn't fully 1 G
as before, you spin, but with platforms and proper angles you get a vector sum of forces, i.e. 1 G without it all coming from spin
less spin force means lower costs, higher safety factors
also, you are more able to build fail safes because you have ground to set up anchored breaking fail safes
cheap? not on your life, but an interesting possibility

Says who? and why? This is straight conjecture. High gravity is not required for humans or animals to survive long term.
We have many, many years of experience in microgravity. We know exactly what it does. There is no "accelerated aging." It only results in reduced bone and muscle mass over time--which is exactly what you would expect from living in a low gravity environment. There is no reason to think living in low gravity would affect anyone's lifespan negatively. The sole and only reason it's troublesome is the return to Earth.
lets send obama
reduced gravity problems is conjecture, but there is a lot of conjecture about it
sure it's possible it would not be a problem, but it's a very large risk with people's lives
of course if they are willing to take the risk, they're informed adults, but when you get into their children to be born on a low gravity world, that is a moral issue
now on microgravity and it's health risks, what you say is true to a point, people mostly recover from its effects
but as i recall, there have been Russian studies(they have the most experience in long term effects) that showed some effects lingered a long time, some of which included immune system changes
spending your life time in micro gravity could be a non starter at this time, unless you're willing to take some larger risks
well that is a overstatement.

for example, vision problems in men are just one of the new(er) problems they have discovered.
we dont know EXACTLY what it does, because we have only sent 24 men beyond earths orbit, and none of them for an extended period.

with low gravity boobs and balls will never hang low
The uncontrollable osteoporosis is not a negative effect?
Unpreventable 1% loss in bone density a month..
(Apollo 17's three days on the lunar surface is the longest humans have been under another masses gravity. Your definitive language is based on 3 days and 2 hours of observations...)
Youre sure this bone deterioration will end once they reach that 38% Martian gravity?
Why are you so sure?
The moon is 10% of Earth's gravity....Mars is much higher. There's no reason to think living on Mars would be dangerous to human health. No, bone and muscle loss isn't a problem ..... in space. It's coming back to Earth that's a bitch. The main problem with living in space seems to be too much blood flowing to the upper extremities. I am sure this is a problem that genetics and/or medicine can cure.
WRONG AGAIN.
The moons gravity is 16.7% of Earths (roughly 1/6th).
Your osteoblast and osteoclasts evolved on Earth (READ: Earth's gravity). It has been demonstrated they function incorrectly under different gravitational effects.
WHY IN THE WORLD WOULD YOU ASSUME THEY WOULD WORK FINE with the Martian 38% gravity?
at BEST youre assuming "human bones will 'level out' on Mars, and you'll only need 38% of your 'Earth strength". There is ZERO evidence to support this.

Yeah, and you're ASSUMING that there will be a problem. Why would you ASSUME that the human body cant survive anything but exactly one Earth gravity? There have been astronauts in orbit around the Earth for more than a year at a time. The longest person to stay in space continuously was a Russian on Mir, who was there 431 days. After he returned to Earth he walked on his own legs from his Soyuz capsule to a nearby lawn chair. He wasn't crippled. He might have lost some muscle and bone mass, but that mass is regained over time. The human body is remarkably adaptable and resilient.
you could drop a payload of humans on the red planet, hope for the best
but then, you could land a self contained environment with man's long suffering servant, the lab rat
if rats can make in martian gravity, it's a good indicator other mammals might make it
and the cost ought to be much more doable

^Earth's gravity is getting stronger because all the fat Americans. lol
