The idea of finding and raising the Titanic was thought of very soon after the sinking of the vessel. However, the first successful attempt at locating the Titanic Wreck was in 1985 by a French and American expedition led by Jean-Louis Michel and Dr. Robert Ballard.
The higher the pressure, the harder the heart has to pump. Normal adult blood pressure is defined as a blood pressure of 120 mm Hg1 when the heart beats (systolic) and a blood pressure of 80 mm Hg when the heart relaxes (diastolic).
The pressure measured when the heart contracts and pumps the blood into the vessels is called systolic blood pressure, and the pressure measured when the heart relaxes and fills up with blood is called diastolic blood pressure. The unit of BP is millimeters of mercury (mmHg). The normal blood pressure range for adults is 120-80 mmHg (systolic should be below 120, while diastolic should be below 80). The ideal blood pressure for men and women (even for women over 40 and for women over 50) can be slightly different.
