1. There are also indications that ‘outer space’ humans on might gain a mutation that raises their survival advantage.

2. If coming to Earth there neurology aspects.
Children are born with exact parameters to interact with Earth gravity in a healthy way.

Looks like to be extraterrestrial born makes one alien for Earth (except a short artificial gravity adaptation - and back).

Which Way Is Up? Neurons That Infer Direction of Gravity Discovered - Neuroscience News (

- People are intuitive physicists, knowing from birth how objects under the influence of gravity are likely to fall, topple or roll. In a new study, scientists have found the brain cells apparently responsible for this innate wisdom.*

- In a part of the brain responsible for recognizing color, texture and shape, Johns Hopkins University researchers found neurons that used large-scale environmental cues to infer the direction of gravity. The findings, forthcoming this month in the journal Current Biology, and just posted online, suggest these cells help humans orient themselves and predict how objects will behave.

I think it would be frustrating and disgusting to have diarrhea in weightless space.
Vomiting is also bad.
Imagine if in a Helmet space walking.

The Japanese experimented with little fan packs to get around with in a capsule. When they were on the ISS. I don't know how that worked out.
But hey it was a good idea, the fans were activated with hold down button on them. So they wouldn't get carried away with it. A little push here and there.

One of them would probably be the inability to shower. Astronauts use wet wipes to clean themselves off which, yeah, that works, but it just can't really feel the same.
