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).
This is called systolic blood pressure. A normal systolic blood pressure is 120 or below. A systolic blood pressure of 120-139 means you have normal blood pressure that is higher than ideal, or borderline high blood pressure. Even people with this level are at a greater risk of developing heart disease.
