In the medical field, the word "normal" isn't specific. What is normal for you is not normal for me. 120/80 used to be the "normal", but now we have found that is no longer the case. It is now simply a referance to go by, but should never be considered "normal". My wife's blood pressure usually runs about 100/70, but sometimes dips to 94, you thikn she has hypotension? No, because that is perfectly normal for her.
