Half dark half normal: the chemistry of turds?

Don't know, but the brown colour of excrement is caused by a compound called bilirubin (not sure of the spelling) and this is a hydrogenated porphyrin. Porphyrinato compounds can lose energy by oxidising and the part in contact with the air could do this more rapidly and hence change colour. Not sure though.

Firstly, I do not buy into the doctrine of either none or lots.  Now then with that said, let me share some data with you.  When I was 23 I got seriously drunk and I went to the toilet and hung my head over the edge of the bowl and I puked and puked then dry heaved until I went to sleep.  When I awoke and noticed all those different pubie/pubic hairs all so variously adhered to its rim with that foul mix of dried yellow dots, I told myself, "I'll never get drunk again."  Now, I know some folk are full of fecal matter and such a self=promise wouldn't amount to a hill of digested beans.  I'm now 62 and that was 39 years ago and I have not been drunk!  I will not drive if I have drank more than two beers and if I come to visit whoever, if a snack included I will drink another if time is in my favor; like no tanking.  They say if three beers a day, then that person is acoholic; I am therefore an alcoholic.  I generally slow-sip about five or six beers per day.  Text-books of medicine proclaim a shot of whyskey per day is beneficial for longivity since it does some beneficial things within your body.  So, when say stop all, I realise they are coming from ignorance and know not what they are saying and I correspondingly bid them a nice day.  I have a bunch of long-term associates and my drinking has never alarmed any of them because they know I will not drink into a stupor and my mind remains entirely sensible.  I suggest to all, if you prefer a beer to a soda, have at it; but by all means, do drink responsibly.  So now you know why I do not listen to a smacked idiot.

Not necessarily. A lot of people assume the blood and guts and all other types of stuff will ooze out and junk like that but in reality this is not so. Usually the blood is already drained out, and the inside is actually clean, (although smelly) to allow you to clearly see all of the parts and so forth. It can be quite interesting actually.

We all have different amounts of melanin in our skin. If we have less, our skin is lighter. If we have more, our skin is darker.

probably dirtier than the whites\nas in runny nose due to more spices

some have a bleaching agent in

Surprisingly, very little.  It depends which organs you're talking about, but it's not full of blood or water, really, not like what you'd think from cartoons or something.

The answer would depend on the color to the samples.  Since dark colors absorp(Suck in) heat easier, black dirt would be warmer than tan sand if the were both in the same temperature and sun

I have wondered the same thing. Actually, I wonder how one of those turds that seems like it takes forever to get out breaks into like four smaller pieces. I do think it has to do with the size of your sphincter or what you eat. I noticed that when I eat a lot of wurst and kraut that I release a lot of short fat turds but when I eat a lot of vegetables my turds come out long and thin.\n\nPS: There is a science called Scatology that studies turds.

There is a breakdown product of hemoglobin (a major component of red blood cells) called bilirubin.  Bilirubin is eliminated through urination and defecation but it breaks down into the other products.  One of the products is yellow (so that's y pee is yellow)....the other product is brown (and that's y poop is brown)

To steal an answer recently posted by someone else, it simply comes down to the lack of need for dark pigmentation at high latitudes.\n\nAt low laititudes the risk of death or illness from skin cancer is higher than the risk of death from rickets. As a result people who lived at low latitides retained dark pigmentation since that provides portection from skin cancer. \n\nNote that it isn't only Asians that retained this trait.  Southern Europeans are no more or less prone to having dark hair than Asians.\n\nAt higher latitudes the risk from skin cancer declined and the risk of rickets increased. Having pale skin reduced the incidence of rickets, so pale pigmentation evolved through a reduction of eumelanin\n\nOne of the side effects of of low eumelanin levels is that it allows for multiple hair colours as well. With no eumelanin at all hair can be blonde, or it can be red colours that are difficult to achive in skin that  has high levels of eumelanin. With moderate levls hair can be brown, and with normal levels the hair can be black.\n\nPeople with normal eumelanin production can only really have one hair colour: black. That's because eumelanin covers over any other pigments.\n\n\nYou will note that it isn't only Asians who have almost exclusively black hair. It is equally Negroes, San, Aborigines, American Indians, Negritoes and so forth. European were freed up by their pale skin to express a range of skin colours not seen in normal humans.\n_________________\n\nMay said "the alleles are inherited and contained in the >>>>>>>same race."\n\nUtter Bollocks. If you are going to answer a question at least have some idea what you are talking about.\n\nThere is no such thing as a biological race. There are no alleles for black hair that are contained within the Asian race.

Some years ago, a friend at work used to make lunches for colleagues. They consisted of minced meat and vegetables with chilli and other spices inside pitta bread. He'd gradually increase the chilli content according to a scale he devised. I had just moved up to level 2 (of 5, I think), but at the time I was not used to piquant food. These lunches started to affect my whole body, upsetting my digestion, and even making my urine smell of the strong spices.\n\nOne day I was sitting on the toilet at work, dealing with the consequences of a previous lunch. This particular men's room had just one cubicle and two urinals. I heard a guy walk in to use a urinal, but I wanted to fart. I could feel it inside me. At first I thought: "no, I can't do it, this is the only cubicle, and he'll hear me". But then I thought: "that's ridiculous, what does he think I'm doing in here? And anyway it's only going to be a little chuff - he'll hardly hear it".\n\nSo bravely I released the "little chuff". I didn't force it, I just let it go. But this was no little chuff!! This fart was absolutely ferking enormous!!!! It exploded out of my backside, thundered round the pan, boomed about the cubicle and resounded around the entire men's room.\n\nFor a split second I was frozen in jaw-dropping, surprised shock. Where did that come from? [Well obviously I knew where, but it was completely different to anything I had expected.] Good grief!! How did that happen???!!    \n\nBut then, almost immediately, from outside the cubicle, I heard the horrified, and deafened, urinal user whisper loudly: "JEEssusss ccchhrriiiSSSTTTT!!!!". And then it was all I could do to contain myself, and stop laughing out loud. From fart through shock to near hysterics, and all within the space of five seconds. \n\nI had to wait till the place was empty again, before I left. After all, I didn't want to be identified as the man with a cannon for an anus. But it's a story that subsequently has brought tears to the eyes of amused listeners, and it's something that I'll never forget. Ah yes, such happy, treasured memories.

Its brown colouration comes from a combination of bile and dead red blood cells. In newborn babies, fecal matter is initially yellow/green after the meconium. This colouration comes from the presence of bile alone. In time, as the body starts expelling excess dead red blood cells, it acquires its familiar brown appearance. Throughout the life of an ordinary human, one may experience many types of feces. A "green" and sometimes "clay-like" appearance to the feces is a result in a lack of blood cells expelled. Bile overload is very rare, and not a health threat. Food may sometimes appear in the feces. Common undigested foods found in human feces are seeds, nuts, corn, and beans, mainly for their high fiber content.

you'll have a lot of good ol' beta carotene in your system :) the worst thing i could think of is your skin or urine might look orangy. but that's just normal. sometimes i eat red beets and my pee turns red.

Not sure what the DARK REALITY means, but taint is the skin between a woman's vagin and butthole and qweef is a pu$$y fart so it doesn't make sense at all.
