Why do old people fart in public?

Because they can=)JK.

There are a lot of reasons that cause flatulence, from diet to diseases but mainly as you get older your sphincter muscles are not as strong as they used to be. So actually, old people fart everywhere, not just in public.

What is the purpose of a colonoscopy?

The test is frequently used to look for colorectal cancer, especially when polyps or tumor-like growths have been detected by a barium enema examination and other diagnostic imaging tests.

It allows a doctor to look inside the entire large intestine. The procedure enables the physician to see things such as inflamed tissue, abnormal growths, and ulcers and commonly used to look for early signs of cancer in the colon and rectum. It is also used to look for causes of unexplained changes in bowel habits and to evaluate symptoms like abdominal pain, rectal bleeding, and weight loss.

Why do some people feel warmer than others?

Body temperature is an individual thing. The average body temp for people is 98.6 degrees, but that is only the average. Some people's body temp is 97 degrees and would be feverish at 98.6. The human metabolism will increase and decrease in speed depending on many different things. Could be almost anything, different medications will speed up or slow down metabolism which us humans being endothermic usually maintain a constant temperature usually between 96.4-98.8. 97.4-98.6 being an average for a healthy human all year around (I am attempting to give you a broader range with the #-#). Once you start to hit 99.6, you are considered running a fever for any number of reasons, usually illness or in some cases heat stroke (but heat strokes tend to make you quite a bit hotter, we are talking about your body cooking itself). Temperature might be constantly maintained in endothermic animals by means of using ones own chemical process to keep within temperature parameters for life to function, but still varies of course. Fatigue or simply the sleep response will decrease body temperature, ever have a rough day at work and your muscles hurt so you just want to lay down then sleep? That's because it is the body's way of repairing itself, the sleep response is triggered by a number of things which in turn decreases your body temperature to help settle down for rest. That is only one possible reason which happens quite often for anyone at anytime during the day. Another main possibility is body mass and muscle to fat ratio, the more fat you have on you the warmer you will be, seeing it is extra fuel to be burned and also acts as personal insulation. The bigger you are, the more energy it requires to run you, the more raw material converted into energy in which more heat is produced. Also, the more active you are and the more you challenge your body to do some work and burn that fuel you have stocked up the more heat you will naturally produce as a by-product of simple processes like air to carbon dioxide and fat to carbs/calories to energy (vice versa too[only for the "fat to carbs/calories to energy" though]). Could be something as simple as the temperature that you are relatively used to being in. Someone from Florida that is used to 75-100 degrees in the Autumn goes up to Ohio and complains about it being cold, where as the Ohioan says its nice n warm or slightly nippy at 50-70 degrees. It is estimated that 76 degrees (no wind) is the average comfort level for most Humans(assuming you are not wearing clothing). I cant say that Gender plays an extremely significant role in determining who diffuses body heat at a faster rate. If i had to guess i would say the guy would retain heat better than a woman of the same age and height with average build seeing men tend to be a bit more dense and have a larger torso to retain most of their heat where most metabolism takes place. This is a very very broad question to be answered by us telling you alone. There are about a million different variables can that contribute to body temperature and perception(personal tolerance if you will) of warm and cold. The main influences (I hope iIgot some of the major ones) are the ones I mentioned above that adjust the temperature of a endothermic animal on a larger and more frequent scale than others. At all times your body receives information from sensory input and adjusts you to compensate for the variances in the immediate environment(this should be the biggest one). Example being when in a cold environment your body involuntarily shivers as a precaution to keep you active and warm. Keep in mind that there is alot about the human that we do not understand yet, there are a ton of mechanisms from our ancestors that have been built into us from many years of experiencing the same thing over and over. The unknown could be a reason that influences temperature, I do not know, just throwing out of the box answers as a possible cause. It would be best if you would go to a search engine and look this up, its your best bet on finding a complete explanation to such a large and uncertain question. Sorry for the run on sentences, my English is getting a bit rusty. Someone fix anything in this post soon as they see it and dont like it.

Is streptococcus a resident biota of the gastrointestinal tract?

It depends on the species. For example, Streptococcus bovis is usually found in the large bowel and it causes infectious endocarditis in people who have some diseases in that organ and have some cardiac abnormality. As for Streptococcus pyogenes, it can be found in the pharynx (throat) of some people as colonizing bacteria, and in others cause disease (amygdalitis), but it's not supposed to be found in most people. Streptococcus pneumoniae, which is the most common cause of pneumonia, sinusitis and otitis media, colonises a large number of infants, and can also cause disease if the conditions are favourable. Streptococcus viridans causes teeth disease and is part of the permanent micro-biota of the mouth; if imbalance occurs, then it can cause some problem. Enterococcus are a group of bacteria that also belongs to the major group of streptococcus, and, as the name says, are found in the large bowel, rarely being a cause of infectious endocarditis or urinary infection (of the bladder).

What is erythematous mucosa in the antrum?

Mucosa is the lining of cavities that are exposed to the outside environment, such as the nasal cavities, and internal organs. Antrum is a general term for a cavity or chamber which may have specific meaning in reference to certain organs or sites in the body. Erythematous means unnaturally reddened.

So, erythematous mucosa in the antrum means that the lining at a site in your body is unnaturally reddened.

If when the AC is running some parts of your house feel almost too cold while others aren't cool at all what causes this?

Hi: I'm going to attemp to help by minimizing answer same way as you minimized your question.Assuming it ever worked right at all, Think back hard and try and remember if any work has been done in the area where that duct work my be. If so you may have crushed or disconnected ducts to those areas. ( seen it bunch of times )

Also, Never assume whomever installed it did it right in the first place. Seen plenty of dunder head pros. Thankfully you can get your own calculation guides and figure for yourself you basic needs. Though not a pro. you may be surprised how effective you can be.

If you are trying to heat/cool a two story house with one system you needed a better than average dude putting it in to say the least. Plenty of kewl things you can do to make it work, (BUT) most don't know them, or bother if they do.

Hope this helps: Ask more if you need, Jimiwane

air flow dividing is a function of the ventilation duct layout. if it was built by a certified HVAC contractor, it was laid out prpoerly, and was later tampered with or has developed a blockage. If you know something was done to ducting or vents, that is probably where the trouble was started. Re-establishing flow balance is not simple, it requires some knowledge and some math. call a HVAC tech, and get help there. I could explain it, but you would still get it wrong, it involves too many specific variables.



Assuming no one has disturbed the ductwork with remodeling, etc. . . . There are two solutions.

The first temptation is to close the air supply duct in the room with the thermostat. It will still get some circulation from the other rooms. Unfortunately, they will be too hot in winter and too cold in summer, so you'll have to tinker with the thermostat setting, which may work reasonably well unless the outside temperature is severe. Your mileage may vary.

The second solution is the one I use, and I'm extremely satisfied with it.

When the A/C cycles off, any house heats up more in some areas (upstairs or sunny rooms, for example) than others (basement, north-facing rooms). The thermostat is in a single room -- that's the only room that stays at a reasonable temperature. All the others are too hot or too cold no matter what season.

I stay comfortable everywhere by employing the same concept used in commercial buildings -- run the FAN all the time, and let the A/C (and furnace) cycle as needed. You'll find this also stops all those creaking and popping noises the ductwork makes as it expands and contracts with every cycle, since the temperature swings are much smaller and more gradual/gentle.

On every home thermostat, you'll find a switch that has nothing to do with the temperature setting, marked OFF / ON / AUTO. Yours (everybody's) is set to Auto, so the A/C (and furnace) automatically turn the blower fan off and on as needed. The fan cycles late so the unit can come up (or down) to temp, then continue to bleed off some residual energy from the unit after the unit has cycled off. If you switch it to OFF, nothing will run.

But, if you set it to ON, the fan will run constantly. (This is the setting you want).

You'll find the basement gets dry so it won't need a de-humidifier (and all the little critters die), the upstairs is cool, and the entire house is always comfortable. (Works great in winter, too). You're constantly circulating all the existing room air to all the rooms, so they all remain about the same temperature. If you find one room is too cool, slightly adjust the air duct in that room only.

It would be ridiculous to use the same system in a large commercial building that you use in your home (i.e., fan cycles on only when heating or cooling is called). Large buildings run the fan 24/7 and modify the amount of heat or cool that goes into each room by using multiple thermostats spread around the building.

The downside is that you'll need to oil your furnace's blower motor every few years instead of 'never'. It's easy to do, even though you've never done it before.

Buy a quart of 5W-30 synthetic oil (about $4, lasts far longer -- Mobil 1, for example) from an auto supply store. While you're there, ask for a 'zoom spout' oiler (about $3). It's a small bottle with a long, narrow snout that puts oil into tight places. Switch the oil in the bottle with the synthetic. Put the unused oil in an old shampoo bottle for later use (yeah; like that's gonna happen).

Turn off the main electric power to the furnace. There's a wide rectangular hole in the front of the furnace that lets air into the combustion chamber. Below that is a cover over the blower fan and motor (you'll see the return-air ductwork on the side). Just pull off the lowest cover from its top edge. You should see a weird little push-switch that automatically turns off the unit when the bottom cover is removed.

Inside the box you've just uncovered, you'll see a large rounded tub shape. Pull it straight toward you and it will (grudgingly -- it's just sheet metal riding on sheet metal) slide out about halfway.

On one side you'll see two long plastic tubes that look like drink straws, open at the top (the other end goes to each motor bearing). Pull the 'zoom' out of the zoom spout, put it in the tube, and fill the tube with oil. Repeat with the other tube. Put the cap on the zoom and then push it back into the bottle (in that order or you'll get oil on your hands).

Push the blower back in, replace the cover, turn on the power. Do not disturb the squirrel cage fan -- it has been carefully balanced with little counterweights. Time: about 7 minutes. After you've done it once, about 5 minutes. If you forget and it runs out of oil, it will squeak.

Repeat every 5 years. Trust me -- once you realize how comfortable you are all year 'round, you'll never regret it.

Or, you could just go back to the 'Auto' setting and be right where you are now. Miserable.

This is great practice for the unlikely event that your furnace blower motor fails (it doesn't happen often, but it does happen, and often in the dead of winter). You can replace the motor for about $35-$40 and a little bit of your time and effort and an Allen wrench (we use Grainger Supply), or pay someone about $400-$500 to do it for you when they get to you. It's your choice.

Why no alcohol within 24 hours after a colonoscopy?

The main reason to avoid alcohol following a colonoscopy is because you were given intravenous sedation and pain medication during the procedure. This is also the reason why you are not allowed to drive yourself home after the procedure.

The two medications normally given are 1) a narcotic analgesic (painkiller) - usually Demerol (meperidine) or Sublimaze (fentanyl) and 2) a benzodiazepine (sedative/hypnotic) - usually Versed (midazolam) or Valium (diazepam).

One should NEVER mix alcohol with narcotics or benzodiazepines. Doing so may cause severe reactions including death.

Incidentally, I had a colonoscopy today and asked the same question before I left the Gastroenterologist's office.

Why can't you drink alcohol within 24 hours after a colonoscopy?

Colonoscopies and the preparations for them remove much of the mucous that protects the intestinal tract. Without it, alcohol (which kills unprotected cell tissue) will burn the inside of your intestines.

Why do bones pop?

It's not the bones the pop. Sometimes you get little air pockets in the tissue that is between your joints and that is what causes the pop sound.

Joints are the meeting points of two separate bones, held together and in place by connective tissues and ligaments. All of the joints in our bodies are surrounded by synovial fluid, a thick, clear liquid. When you stretch or bend your finger to pop the knuckle, you're causing the bones of the joint to pull apart. As they do, the connective tissue capsule that surrounds the joint is stretched. By stretching this capsule, you increase its volume. And as we know from chemistry class, with an increase in volume comes a decrease in pressure. So as the pressure of the synovial fluid drops, gases dissolved in the fluid become less soluble, forming bubbles through a process called cavitation. When the joint is stretched far enough, the pressure in the capsule drops so low that these bubbles burst, producing the pop that we associate with knuckle cracking.

It takes about 25 to 30 minutes for the gas to redissolve into the joint fluid. During this period of time, your knuckles won't crack. Once the gas is redissolved, cavitation is once again possible, and you can start popping your knuckles again.
