Marc and Dan are twins who like the same activities, and foods. At a recent doctor's appointment, Dan was told that he has type 2 diabetes. He has been feeling good and has not noticed any changes in his health. He does not understand why he has diabetes, but his brother does not and why he has not had any noticeable symptoms. How would you explain this to him?

Type 2 diabetes isn't genetic, which means that Dan got diabetes from the foods he eats and his exercise habits. Marc doesn't have type 2 diabetes probably because he exercises more than Dan, or simply because his body metabolizes his foods faster than Dan's body does. Dan also shows no noticeable symptoms because he most likely keeps his blood sugar levels at a healthy rate without noticing or doing this on purpose.
