Personality and Alzheimer's Disease
Q: What is the average speed of circulating blood in your body?
a) 1-2 miles per hour
b) 3-4 miles per hour
c) 5-6 miles per hour
d) Less than 1 mile per hour
A: b) 3-4 miles per hour, but that's just the average. Flow is faster in some places, slower elsewhere (for purposes of improved tissue oxygenation). Blood pumped fresh through the heart's aorta moves at an impressive 15 inches per second, or 10 mph.
"Oh, you young people act like old men. You have no fun." -- French American entertainer and activist Josephine Baker (1906-1975)
