@zeccano

I stopped reading after the first sentance... more nonsense.

If you arent here to learn then bother someone else, my time is better spent on others.

@CCoinTradingIdeas

@chikara

You are welcome to ask me any questions you like. I try to answer them as best I can within reason.

If you feel I havent answered a question in a way that satisfies the ask, then please, just ask again and try to rephrase it this time. I'll do my best to answer.

@khird

@Absinthe Anexdotal evidence, I know plenty of old women in societies who wear bras that sag just as much.

I think you may have a misconception because in our societies breast implants are far more command (And rarely admitted to) as compared to tribal societies. Then there is also the question of genetic tendency between the two groups.

I think if you want to make that case and convince me youll have to show a peer reviewed study with some controls. While I dont remember where i got the info from I do know i originally read it in a peer reviewed study which im much more likely to believe than anecdotal evidence like you suggest.

@Absinthe It feels like your really stretching to try to justify a specific line of thinking, perhaps because you have some aversion to the impications of rape being an inherent quality of cavemen humans.

The fact is, humans **do** need to carry fat, if we didnt then we wouldnt. We carry fat because despite the additional energy it costs we need an emergency store of energy we can call on during the winter or other times where food is scarce. So there is a biological need to maintain fat.

Since we are rtetaining fat anyway, and there is a need to do so, then causing that fat to be focused in one area over another has no additional caloric costs associated with it, especially considering that breast fat can be lost like tummy fat and serves much the same functional role

@Absinthe I could see that argument, but when ive read research on bra usage in the past (granted this was years ago) they did not find that using a bra preventing sagging in any way. Sagging is apparently a natural process that comes wiht age and occurs independent of bra usage.

@Absinthe No it has zero cost to concentrate fat from the stomach to the breasts, persuming overall fat on the body is unchanged... 0.

You do realize when a woman with large breasts starves she looses the fat from her breasts just as a person with fat in their tummy would. The cost is the same, the process is the same, only the location is different.

@danie10 For that I will need to check. I know they their policy is not to ban commercial accounts. Or are you saying that their polciy is to ban commercial accounts that sign up?

@Absinthe So its the same fat they would have had in their belly, just moved to their breasts, So it is no high a cost than it was before

@Absinthe There isnt any more nutritional requirement to maintain breasts size, almost none. Genes for breasts merely divert fat deposits that would otherwise go to other parts of the body to the breasts. Its just a redistribution.

@danie10 I covered that in my original message, qoto has no ads, other instances prohibit it as well. But many instances do have adds including Mastodon.social (MS) in their local timeline. Worse yet even if your local instance doesnt have any that means the federated feed will have a few at a minimum.

@Absinthe That would be a fair point, except women who have back problems have those problems with or without a bra. In fact a bra would raise the center of gravity and add more strain on the lower back

Ther eis a valid counter-point to the rape explanation, but it only goes so far.

We could argue that it plays a similar role to enlarging butts, that is, it is a secondary sex characteristic that signals to males a woman is ready for sex and the ability to bear children.

While this is likely true, and partly a pressure for breast growth it doesnt explain why it was able to evolve to the point of causing physical harm, which brings us back to the original problem (And thus why rape is still likely an element as far as I can see)

@Absinthe Yes, but again the color change has no negative impact, therefore it is not unusual nor comparable to women with large breasts to the point of back problems.

@Absinthe What is unique here is not that we have some arbitrary form to signal our sexual interest (breasts). bur rather that it has negative impact on the health of our women, something that is quite odd.

Most sexual signaling either has no harm or benefit in and of itself, or also serves to have some beneficial aspect (for example with apes enlarged buttox has a functional advantage).

Now why this is unique in humans is a matter of speculation but I offer its because in the past rape was common among humans and thus acted as a signaling pathway, which now as we are a more evolved species is no longer a positive thing but rather fairly negative. But it is simply that our minds evolved quicker than our sexual signaling.

@Absinthe Butts arent equivelant because they serve a functional need. Unlike breasts which do not have a function need prior to child birth.

@Absinthe If that were all it was then why dont other animals have breasts to signal they are healthy in a similar way.

But animals dont walk upright, so larger breasts wouldnt significantly prevent their ability to escape rape (Since breasts are below their body along their center of gravity).

Moreover, we can easily see someones body fat regardless of breast size, so the breasts dont really help in that regard anyway.

@Absinthe well thats just a matter of semantics. Point is, chimps and no other animals have "bulbous" breasts prior to child bearing.

So whatever you want to call it, it is very unique to humans.

For those who arent on an instance with math rendering you can read the answer here: http://mathb.in/38503

In the language of math the key is in how we frame the question. For example the following will provide some insight as I will show in a momemt.

\(\exists n \in \mathbb{N}\) such that \(n^3 - 1\) is prime

Not everyone understands the above notation so let me rephrase it more simply. The above translates to "There exists a Natural Number, \(n\), such that \(n^3 - 1\) is prime." Remember a Natural Numer is any positive Integer. In this example assuming that the original assertion that "8 is the only perfect cube to follow a prime" then \(n = 2\) which means the prime number, \(7\), is \(2^3 - 1 = 7\), and \(8\) is just \(2^3 = 8\). Easy enough, but how can we prove that this is the only case...

So we really just need to figure out which values for n in the equation above will give us a prime number, then we have our answer. A prime number is any number which only has 1 and itself as its factors. In other words the only two natural numbers we could possibly multiply together to get 7 is 1 and 7. So we have to start by factoring out the above equation \(n^3 - 1\), if we do that we get:

\[(n-1) \cdot (n^2+n+1)\]

It should be immediately obvious that of these two factors the left-most one is the smaller number, so we know:

\[(n-1) < (n^2+n+1)\]

Since we only care about prime numbers which satisfy the equation we know the left hand term must be equal to 1 and the right hand term most be equal to the entire number. So we can likewise assert the following:

\[1 = n-1\]
\[n^3 - 1 = n^2+n+1\]

Now we can use either equation and solve for n. It doesnt matter which equation you solve they will both give you the same value for n. Solving for n we get:

\[n = 2\]

If we plug that into the original equation, as we said earlier, er get the answer of 7, therefore 7 is the only prime number followed by a perfect cube.

\[2^3 - 1 = 7\]

@Deepsealioness Pretty good, went into the city this weekend and enjoyed some Sinterklaas goodness (food and decorations)

@Absinthe But the point here is simply that sometimes we dont evolve things that are to our advantage, sometimes it is simply for sexual selection. Or it could be for archaic reasons.

For example it is possible women evolved larger breasts in caveman days simply because women with bigger breasts had a harder time running and thus were raped more often, so it became more common. It may have signaled to a man an easier to rape woman and thus selected for.

In the modern age we would see it as negative of course even if to the mechanics of evolution it may seem to be selected for.
