Should i be concerned if my friend is suffering from achondroplasia, wht is his percentage of diasability?

Can be a plus: I know a couple of achondroplastic dwarves and they like it -- one is an orthopedic surgeon treating other dwarves. He dislikes being called "handicapped / disabled". Let your friend decide how he/she feels about it all, and accept whatever she chooses. She's already gotten advice about how her being a dwarf affects accommodations that others must make in the workplace.
