Yawn. Gravity is the one thing that has been basically constant for all of human evolution. Sure there are unknowns, but one of them certainly is not that long term exposure to just 0.38g will result in, amongst other things (reduced bone density, reduced circulatory health, etc), a significant degree of muscle atrophy. How completely any deleterious effects of 0.38g can be effectively countenanced in the long term is anyone's guess for now - but a starvation potato diet certainly isn't going to make any future suggested cures list.
