• One identity might be allergic to cats; another isn’t.

• One alter may be diabetic; the next registers normal blood sugar.

• EEGs, heart rate, handedness, and even vision have been shown to vary dramatically between personalities.

• And yes — there are cases where eye color was reported to change between alters (Putnam, 1989; Braun, 1986).
