      It definitely would. Our bodies have evolved to work to the gravity of the earth.
      If we live on other planets where the gravity is less, we won’t be able to walk and move the way we’re used to and our muscles will degrade.
      And if we lived somewhere with more gravity, it would be really difficult to walk and we’d get really tired really quickly!

      Good question!
      Gravity effects everything that we do on earth – and Roma’s right, we’ve evolved to function at this level of gravity.
      Living on another planet long term would mean our bodies would have to adapt – somthing mankind has been doing for the past few million years! It’s not something that would happen quickly!
