did you ever pass through Philadelphia? if so what were your thoughts on it? also did you ever have to spend a winter in a northern city or state and struggle to find a warm place to stay, or did most of your winters take place in the south?

Hi, I am a high school senior looking to go into materials science in college next year and am taking a high school level course on nanotechnology and another where we use a 3d printer. I am wondering what will happen to the splints when the babies grow? will they need a new one or by that time will the body have healed the airways?
