What about lead undergarments?
There was a certain manga I read where it will take generations to adapt to space.
Those born in space (mars, other planets) will adapt to non-earth conditions so it will be easier for them to travel. Those of earth will have a harder time to adjust. In addition, in this manga series, they had to clone humans who can easily adapt to space radiation like it was a normal thing.
And why do they have to report this in SI units?
