Well... first cosmonaut candidates (and many after that) were military pilots. So no wonder that they lived in military camp.
Also about appointing first cosmonaut by looks is not something strange. After all strict selections there's almost no difference among final candidates in health condition, skills or cognitive abilities. They are all as healthy as human can be and quite smart and trained. So final pick by these criterias would be pretty random anyway (even now for modern candidates it still is).
And given that sending first human in space was a big deal about political prestige it's no wonder that it was made by the looks of candidates.
