1. Hannah Kritzeckhttp://i.huffpost.com/gen/2595588/images/o-TINY-DANCER-1-facebook.jpg
She is a teenager suffering from primordial dwarfism (very rare kind). There are just 100 human births with this kind of defect worldwide. She is 39 inches tall.
Hannah weighs less than 30 pounds and also looks like a 5-year old lady. Kritzeck is said to be a happy individual even after knowing that people suffering from this sort of problem don't survive after they turn 30.
Yet, she wants to pursue singing, dancing, and acting.

Normal humans have 7 vertebrae in their neck. Fu has 10. It prompts people to call him "Giraffe", which isn't really depressing as much as the fact that three additional vertebrae keep him in severe pain. It restricts his movement as well.
