Maybe in their heads, but I expect we will find all sorts of terrible side-effects. Though I suppose, Star Trekkian medicine can easily deal with those. I doubt it would be comfortable for most people though (and people sure do like their comfort). I mean, look at that description: "half a mile higher than Everest" - that doesn't sound fun to me. Of course, the domes can probably easily dial the gravity up as part of their life-support.
In real life, mark my words: Living on Mars is going to suuuuck. Presumably we will find out soon enough.
