During my previous two posts viewers have asked about grading either because they have had difficulty with it or because they want to know how to select PCGS- or NGC-gradeworthy coins. Each denomination requires different skills. The Morgan dollar ranks among the easiest to grade because of its generous fields.
Over 1,500 Gallons of Blood Pumped Daily The heart is a powerful muscle that beats without stopping throughout a lifetime. It pumps about 55-80 ml (1/3 cup) of blood with each beat for adults and around 25-85 ml per beat for children. An adult heart pumps about 6,000-7,500 liters (1,500-2,000 gallons) of blood daily.
A person can have around 4.8 - 6.2 litres of blood in their body. Depending on body size, fitness. In a healthy person, all this blood will be pumped by the heart very minute, so multiply the volume of blood by 1440 (60 minutes x 24 hours) and that is how much blood will pass through the heart per day at rest. If exercise is done, this could increase to 40L per minute. 4.8 x 1440 = 6912 Litres - 1825 gallons.
