An octopus has three hearts. One heart circulates blood round the body and the other two pump blood through the gills.
Because it is copper based the blood of an octopus is blue or blue-green.
Heraclitus of Ephesus
Everything changes, and nothing stays the same.
Change is the only constant in your life.
The beginning is the most important part of the work, but keep in mind that the second mouse gets the cheese.
