@sixtyforty (sixtyforty) posted a new topic, subject "Large breasts and carpal tunnel syndrome". It read:

   This post is in response to Are large-breasted women more likely to get carpal tunnel syndrome?
    
    This column (and probably some of the cited research) is based on the misguided perception that D-cup is synonymous with “huge”. However, all D-cup means is that the woman's bust measurement is four inches larger than her underbust measurement. On petite women, D-cup breasts are rather small. A person not familiar with correct bra fitting information would probably think such a woman was an A-cup.
    
    This also means that D-cups vary significantly in breast volume depending on the size of the underbust. A woman who wears a properly fitted 28D has a breast volume of approximately 310 cc per breast (the same volume as 34A). In comparison, a 38D is approximately 850 cc per breast! As you can tell, there's no one size that means “D-cup”–it's large on some women and small on others.
    
    However, many people (including many bra-wearing women) have never been taught how to properly fit a bra. To make it worse, there are bra companies and lingerie stores that are concerned more with selling bras than actually getting women into the right fit. To solve this problem, they come up with strange fitting methods that put the highest number of women into a small range of sizes. They'll tell you to add 5 inches to your underbust measurement or measure your overbust instead. Each of those methods put women in bands that are much too big, and that results in way too much weight being put on the shoulders. 80% of a bra's support comes from the band, and the band can't support anything if it's five inches too big. A poorly fitting bra leads to most of the symptoms Cecil described in this column.
    
    Sadly, it's pretty clear that Cecil doesn't understand bra fitting either since he describes 48DD as “the pinnacle of female beauty”. I suspect that what he's picturing is not what 48DD actually is. (In case you're curious, 48DD would fit a woman who has an underbust of 48 inches or greater. Thin women wear band sizes in the 26-32 range.) This guide is a good starting place to learn about proper bra-fitting techniques.

    Perhaps it is not a case of Cecil not understanding but one of the schoolboys he mentions who in large part believe bigger is always better even though they don't understand what is getting bigger.

    No he doesn't. In a paragraph about breast-reduction surgery he wrote:
    
    > ***Schoolboys ***for whom 48DD represents the pinnacle of female beauty may recoil at the thought, but they might consider the inconvenience of walking around with two ten-pound water balloons hung around their necks.
    
    I hate it when you make me defend Cecil, so apologize.

After which, @sixtyforty (sixtyforty) added

    Exapno Mapcase, Cecil is the one who chose to use 48DD in that sentence. I doubt he petitioned schoolboys and had them write the example. At any rate, his mistake is a common one that is believed by many adults, including women who wear bras. I've been fitted by multiple professional bra fitters who believe you have to increase the band size in order to accommodate larger breasts, and that's simply not how bras work. Unfortunately, their bad teaching methods are pervasive and lead to entire generations of young people who believe that's how to find a bra that fits.

After which, @Irishman (Irishman) added

    Part of the problem stems from the way that measurements are typically stated, e.g. 36-24-36 (to cite a “standard”). The 36" dimension there refers to around the breasts. However, the “48DD” notation appears to be stating a different standard, where you list the underbreast ribcage dimension and then the cup size dimension. By that standard, the typical measurements notation is going to come out something like _52_ -24-36, if we assume the increased (fake) bustage on the same frame as before.
    
    It's questionable how “48DD” got selected. It is arguable it reflects confusion on the part of schoolboys on how the different notations work.
    
    Or, it's Ed's fault. 
    
    But **sixtyforty** is correct that there is a pervasive misunderstanding about cup size notation, as if the letter scale is an absolute volumetric measurement scale. However, if everybody is using the same misunderstanding and roughly scaling the letters to similar sizes, I would suggest what we have is a de facto second scale that just confusingly sounds similar to the scale bra sizing uses.

    Speaking as a 34F who has fitted bras professionally, I would call a D cup “oh what a conveniently small size I wish I was that”
    
    However, notwithstanding the truth of all you write, still I think “over a D-cup” is probably not a bad proxy for “breasts causing strain on the shoulders leading to possible carpal tunnel”.
    
    The D-plus group is going to include small-band Ds - say 28-32D - which are a group at very high likelihood of wearing ill-fitting bras with overlarge bands (you'd have to hunt long and hard to get a 28D anywhere on the high street, and even a 32D is dicey), and are also probably short and generally petite, making it more of a strain for them to carry any weight on their jonathan57@example.com. Then you have medium-to-large bands, who are actually carrying a significant amount of breast volume. So it is possible that the designers of the actual _studies_ had some idea of what they were talking about.
    
    I do agree, however, that anyone who holds up 48DD as a standard of female beauty is talking like a loon.

    High Street is the UK equivalent of Main Street in the US - the main street through town with all the storefronts. Not as applicable to the days of suburbia.

To which @John_W.Kennedy (John W. Kennedy) replied

    Except that a main street is quite likely to be actually named “Main Street”, whereas relatively few high streets are named “High Street”.

    Actually, High Street is by some distance the most common street name in the UK. there are well over 5000 of them, so it's fair to say that most decent-sized towns have a high street called High Street. Cite.

    Another difference is that the high street is always referred to as “THE” high street. Main street is not called “the” main street.  
    (And now that we've settled this important issue, can we please get back to the boobies?

    A good thought. I myself have fairly big breasts, and my friend too. We both have symptoms of Carpal Tunnel Syndrome.

To which @Mr.Nylock (Mr. Nylock) replied

    I think this data is too difficult to understand without pictures to accompany it.

To which @MissyKay21 (MissyKay21) replied

    I think it's because big breasted women lean nearer to a desk to rest them there while typing on a keyboard, hence bending their wrists as well, as opposed to stretching the arms further which promotes a more neutral straight wrist position. Hope you got a picture of that.

Then @Exapno_Mapcase (Exapno Mapcase) said

    I think Mr. Nylock is confusing this board with Fark. Maybe he needs pictures to help him.

    Never heard of Fark before today; I looked it up. Meh, it's not really my thing.

    Am I misunderstanding you, or are you saying that large-breasted women (sometimes) rest their breasts on their desks? Wouldn't you have to hunch over uncomfortably for that? Though I guess maybe it's less uncomfortable than having to support them via bra.
    
    How much do breasts actually weigh? Cecil mentions “a couple of ten-pound water balloons” for his 48DD example; is that realistic? What about more average sizes?
