In 1901, a Massachusetts physician named Duncan MacDougall set out to prove that souls have a weight, just like our spleen, kidneys, lungs and all those other things our skin covers.

His often challenged and questionable experiments resulted in his claim that the soul exists and that it weighs about 7 ounces.  

Now that's about six or seven pounds lighter than we come into this world weighing with the physical body. UNLESS, of course, you were one of the Coffey triplets who were born with a combined weight of 3 pounds 0.8 ounces*.  

Peyton weighed 1lb 4.6 oz; Jackson 14.8 oz; and Blake 13.4 oz.  

These little souls became the lightest triplets to survive when they were born by emergency cesarean section at the University of Virginia Hospital in Charlottesville, Virginia on November 30, 1998.
