Rickets are better. They allow you much easier, faster skeletal deformity, and treatability (curing the dang disease) is a huge, HUGE deal in comfort. Healthy children are part of the heedless system that now dominates the medical world in First-world countries, but the benefits are mainly for the pharmaceutical companies, not real people. Once you know of your condition, and IF you can get it there with modern medicine, then it’s fine. But it is really hard to get it there, given that most children are sized small and come with limbs that are necessarily too short to lengthen them more than about an inch and three quarters. That’s not enough.
By which I mean to say, anyone that spends $228 on a quill stem is a fucking idiot.
