The Physics of Breasts

“The professional term we use:” wrote Marcy, “cutlets!”

Marcy, my in-house costumer, was talking about my Cleavage Cupcakes story.

“Cutlets?” Really?

“Cleavage Cupcakes” sound so much more fun and interesting.

And something you might not have thought of, the physics of breasts. Truly, as in Discover Magazine. The American woman used to be 34B. Now it’s 36C. No one reason, but a combo of greater estrogen use, eating habits and…you guessed it, breast implants.

The burden of bigger breasts, though, is real. A pair of D-cup breasts weighs between “15 and 23 pounds—the equivalent of carrying around two small turkeys,” according to Discover Magazine.

I, on the other hand, carry around two little baby chicks. Nice little chicks. But chicks.

“Fifty-six percent of women suffer breast pain when jogging.” And no surprise, women often avoid activities that are physically painful.

To best support bras, designers have to know how they move, and so a couple scientists in Australia have women run on a treadmill with lights attached to their breasts. Computers track the moving lights in three dimensions to study breast movement. “The women run with and without bras, so the laboratory doors are bolted to prevent uninvited people from coming in.”

And here’s the really important part:

“Breasts move in a sinusoidal pattern.”

Even small breasts can move more than three inches vertically during a jog.

No word on whether Cleavage Cupcakes…or cutlets….have any impact on the pogo-stick effect. Or that sinusoidal pattern.

More for science to look into.

    My 38DD’s put me out of any type of high impact exercise a few years ago. I blame it on Estrogen dominance since my hysterectomy in 1993. Trying BioIdentical Hormones presently. Will keep you posted.

    I’m laughing sinusooidally. As long as my boobs doing hit me in the face, all is well.
