I don't tell the doctors anything any more...even personal health information that's none of their business.  What does it matter what my family history is (father, mother, siblings, kids, etc.) if I am there for the flu or a broken leg.  It is just a data collecting system.  I have long stopped answering questions and have become an orphan.  I find that most doctors feel very superior and entitled to all your personal info.  So much so that they get angry if you won't answer questions. LOL...I'm old enough to remember doctors who just took care, didn't push big pharma and believed what you said because you knew your own body better than they did.  I do not like this new crop of young docs...
