Without gravity the muscle has no way to work naturally, it just floats around if you move that muscle, in space you cant lift weights to keep them strong, because like i said everything just floats

Without gravity, your body is not working as it should. In space, you are floating so there's no walking or running to keep your muscles built up so because of this, your muscles become weak.

Hope this helped :)

In Homer’s time, how did people share an epic poem?

Margaret [11]

Epic poems were memorized and then presented to an audience orally. This was required since the vast majority of people during that time period were illiterate. It is theorized that the repetitive structure and recurring syllables present in the epics, were used by storytellers to aid in memorization.
