A lots has been said about, how passengers on elon musks BFR rocket will need to wear space suits and be ready to deal with great G forces. But this concern are very overated because the maximum amount of Gforces that passengers would experience during take-offs and landing would be only 3G.
For reference, the G force experienced on a roller coaster is usually between 3.5g to 6.3 g and people don't die on the roller coaster.
So the arguement about G forces is overblown and sad
