I feel we should probably build massive rotating space stations first, instead of going to Mars. At least with rotating space stations, we can generate 1 g of gravity, to simulate the Earth’s gravity. And you’re still close to home, for when you get space sick. I think if the Mars trip ends in the premature deaths of its inhabitants, because of reduced gravity, then this alone will cause the economic failure of the program. But, alternatively, maybe the solution is to build a centrifuge on Mars, that will spin you around at 1 Earth Gravity. And maybe you need to sit inside this device for 1 hour a day, in order to get your Earth gravity needs.
