Dearest Eyeballologists,

As a sheepy I of course have eyeballs. Eyeballs are my all time favourite part of my anatomy that enables me to see where stuff is.Eyeballs are just great !..I luff them...ewe luff them...we all luff them ! Well done to the bloke who invented eyeballs which I believe was in 1933.


Look..... here are some (use your eyeballs to peruse the below image)

Eyeballs Being Eyeballs Just Moments Ago



I recently heard that people who live in the Arctic have larger eyeballs by 20% than people who live at the Equator !!..

why's that then ? Why Are Human Eyeballs 20% Larger At the Arctic Than At The Equator ?

Does the same apply to animals that live in both areas too ?


whajafink ?



Hugs and shmishes
