I am a 24 year old twin male. My twin brother is about a foot taller than me (6'1"), never had braces, never wore corrective eye glasses, weighs a normal weight for our age, has no allergies, and normal body hair growth. I, on the other hand, am short (5'2"), have terrible eyes, am allergic to everything, have had doctors told me I have bone development of a 7th-grader, have abnormal body hair growth, wore braces for 6 years due to my mouth not having enough space in it, etc. It appears I have always had some form of growth disorder where I never fully developed and that has affected many things. Does anyone have any insight on this?
