Plenty of pictures of cats and kittens but this one is not mine.
Does you mind's memory cells access different memories depending on the position of your head?
I ask because I've noticed over the years of feeding our cats that I have a wide range of memories flash through the noggin when I am bending over. It also occurs a lot when I am on the floor doing exercises at night.
The memories have no correlation to each other. It could be a memory from almost anything. Tonight I thought of buying unique bird suet at a store in Wisconsin while killing some time before an appointment at a paper mill.
Another time it might be a teacher from 6th grade or some fleeting thought from 20 years ago. No rhyme or reason connecting the memory except that my head is sideways or upside down.
Here are some benefits claimed from being in a reverse position. Some are plausible, some stretch the possibility unless you stay upside down for a long time. My sinuses would wreak havoc if I did it more than 30 seconds. https://www.mindbodygreen.com/0-5501/10-Reasons-to-Do-a-Headstand-Every-Day.html
