Why do you think the 23andme results can't be wrong? Many years ago my father was once given hospital test results stating he was terminally ill with a heart condition. He knew he was somehow given a different patient's test result under his name when when his family doctor asked him if he exercises (he does) and the doctor said "That can't be your patient record. You wouldn't be able to exercise if your heart was as sick as the test result states." My father is still alive and exercising regularly today.
