Around 3 weeks of age, give or take, we hear the collective delighted sweet murmuring and cooing sounds of parents, grandparents and the like,  "look, he/she is holding up their perfectly shaped head." Clearly a genius.

We are aware, aren't we, that this incantation, keep your head up, continues, well into forever. 

This not so dulcet command, "head's up ladies" was heard as we paraded through the gym, in our decidedly unflattering one piece, belted no less, grayish colored uniform, praying that we wouldn't have a fire drill that period, which in turn, would require us to be seen by the objects of our adolescent fantasies.

"Heads up". That cry warning us about the spherical object now careening to earth, which, sadly, might have an unfortunate encounter with our skull.

The universal head tilt in abject adoration at your place of worship. Gazing, adoringly, at the icon of your faith. Chin up, eyes upward, a beatific smile on your face.

Why? Is it really to have better posture, to self protect, for other worldly acknowledgments?

I think not.

Heads up is to make our jaw line look better. 

I did a survey. 

 But, alas, it is really hard to maintain that position for long periods of time. Isn't it?  Coupled, I suspect with tripping over objects in our path.

What to do? 

Take your clue from the over 50 crowd. They have found the perfect antidote to a sagging jaw, while simultaneously concealing a decidedly bizarre event happening around their necks.

To wit. The perfect jaw line..effected flawlessly.
