Hi @eni-ola!
I think you failed to add whether the gravity on Mars is higher than on Earth. Supposedly, we'd weigh about 70% less. So fat would be the least of our worries about going to Mars ;)
The temperature changes are also impressive. It will be a great step for mankind to make this project a reality. But I suppose it's many years away.
The development of this proposal is very interesting. Scientists must make sure of all aspects because once they get there there will be no spare parts store nearby in case of failure.
Thanks for sharing :D
