Its best if disaster is faster than brain. Then you do not feel anything.
Did you knew it: that big animals move slower, indeed is due to the length of their neurons connecting muscles and brain. It might be the reason why specfic sizes in animals have not been exceeded by evolution, and where it did, these designs disappeared again. The bigger the body, the more time-consuming it becomes to coordinate the muscular activity to coordinate any movements, reactions, etc.
If you are long enough in size, you might see that your distant tail is burning while you still do not feel anything - the eyes are closer to the brain than the tip of the distant tail.
So much for the dubious tip that if an anaconda embraces you, you should bite in its tail end to make it release you again.
