> potentially declining birth rate None of the athletes are going there looking to conceive. The countries are probably thinking they invested in the training and their athletes will screw it up (literally) by focusing on alternative activities. Well trained people like this can do it in positions that don't put the full weight on those beds. Might even call it part of the training. Or just put the mattress or stack a couple of blankets on the floor. The size of the beds looks similar to dorm room beds, another place famously failing to keep people apart. I really think they went for cardboard more for the sustainability (and costs) angle but "anti-sex" gets the clicks.
