Knifebird 

One of the most dangerous creatures on Earth. One only appears to someone who is really old. Only two people have survived an encounter with one. Little is known about these creatures besides that of their dangerous nature.

You're almost old enough to be in danger of a knifebird encounter, enjoy your life while you can.
