Day 156 : situs inversus

156hearts

Sandy: A friend sent me a link to a very interesting article about how 1 in 20,000 people are born with their internal organs opposite of what is considered normal : http://www.nytimes.com/2013/06/04/science/growing-left-growing-right-how-a-body-breaks-symmetry.html?pagewanted=1&_r=3&hpw&. For example, instead of their heart being on the left side, it is on the right. This morning in boot camp one of the students, C, told me that she has sisters who are identical twins, literally mirror image twins, one is left-handed the other right-handed. C’s sisters had been part of a Minnesota Twin Study when they were younger and that’s when they discovered the left-handed twin is situs inversus, all internal organs are flopped. Quite fascinating!

Above is my failed Rorschach of mirrored hearts. I had to break open a fountain pen cartridge because I couldn’t find my bottle of ink. Since fountain pen ink is designed to dry quickly, I diluted it with water but it still dried too fast. And the paper absorbed the mixture. Will try again for another post.

Sandy’s year long journey – going from being a right-hander to left-hander, and Kelly’s parallel trip as a left-hander doing things as a right-hander.
