Now, Here's a study I'd like to get my hands around

Exept that I'm like- married.

To give you a bit of scientific enticement, I give you the title of the article:

The Physics of Bras
Force = Mass x Acceleration
Overcoming Newton's second law with better bra technology

. . .

To best support breasts, a designer has to understand how they move. To that end, McGhee's team in Australia, headed by biomechanist Julie Steele, tags women with light-emitting diodes and asks them to run on treadmills. (The women run with and without bras, so the laboratory doors are bolted to prevent uninvited people from bursting in.)
Darnit
Computer systems then track the breasts' motions in three dimensions by following the moving lights. "We can actually work out exactly where they're going, how they're moving, and how this movement is affected by bras," Steele says. Breasts move in a sinusoidal pattern, Steele has found, and they move a lot. Small breasts can move more than three inches vertically during a jog, and large breasts sometimes leave their bras entirely. "We have videos of women who, particularly if the cup is too low, spill all over the top," Steele says.



I wonder how long THAT particular study will stay off the internet.

BUT they do make the effort to remind you that this IS a scientific study

"Force equals mass times acceleration," Steele says. "That's Newton's second law. You have a large mass, and it's going quickly, and the force is going to be large. If you have breasts that are slapping down and hitting the chest and having to come back up, they accelerate very quickly." No one really knows the long-term medical consequences of "excessive breast bounce," as Steele calls it. But it can cause pain and is the most likely reason for sagging breasts.

I've had to enable moderation because some bots just can't stop sh1tting where other people want to live......kind of like Liberals.

It's either this or WV...
