I'll struggle to take Elon Musk seriously on Mars colonization or space travel in general until he at least acknowledges the issues that constant nnEMF, lack of the daylight spectrum as experienced on earth, and other issues of the human body's interaction with extraterrestrial radiation could quickly sterilize, sicken, and kill off any long term attempts.

I'm otherwise excited about the concept of space travel, but it needs to be done right and I'm not seeing that.
