Dolphins blow bubbles, too.

Apparently dolphins can sense the water currents in their environment, and take advantage of this rather incredible ability to blow bubbles.

Dolphins understand the real purpose in life: Have fun.

It's absolutely incredible that they can do this -- but the ability to unconciously sense yet conciously manipulate your environment is something that humans do, too (martial arts come to mind here, as does the Force).

What do humans unconciously sense and take advantage of? Gravity, for walking. Body language, for communication. Bioelectrical fields, if you're into psi-type stuff. Ideas?
