A certain frequency in tone can make a human lose control of their bowel movemements.  Mythbusters tested this out.  Did it work??

"The infrasonic brown note can cause a human to lose control of their bowels. Busted Even after testing a wide range of sub-audible and not-so sub-audible noises on him, not once did Adam lose control of his bowels. Some discomfort was reported however, due to the effects of low-frequency sound on the lungs." \n\nWikipedia has all the seasons, episodes, and the results if you are interested.

Ha ha ha. The question is weird unless you are referring to something specific in physics. Otherwiss,\n\nLike Patient who lies down on bed, remains on bed because of gravity :)\nOr Simple stuff like - the stethoscope lets you hear the heart beat because of physical principals of sound movement.

its amazing the questions people come up with, its even more amazing that people answer them. I have a regular bowel movement approx. 10 times a week. Yearly bowel movements bring a whole new meaning to the phrase "full of SH*T"

now, what do you think? logically the answer has to be no, because even if there WAS a gay contortionist who was flexible enough to try, how can your bum stretch enough to fit your head, and even if it COULD stretch enough, why would you want poop on your head?  LOL

Laxatives work in a couple of ways. Some can increase the rhythmic contractions along your digestive tract. These occur naturally to help digest and move the food along the tract. This is called peristalsis. However, if you take too much or take a strong laxative, it can become uncomfortable for the person. \n\nIf this occurs and you need one at another time, ask your pharmacist for a mild laxative or stool softner. It will be a lot less unpleasant. \n\nDo not overdose or take them too regularly however. They can cause incontinence and you can become dependent. I've seen a number of girls become dependent on them for weight loss purposes yet have no idea they are trying to rid a few kilos but may be developing bowel problems. It's not the best way for weight loss!\n\nHope this answers your question!

very interesting...i think that if your head got severed off, you would stop vomiting immediately because your body obviously has bigger issues to deal with now.  i guess it's kinda like when your hiccups magically go away when someone scares you, or when you forget about them.  it's an uncontrollable bodily function that i think can be "side-tracked away."  wish we could test this one...send it in to Mythbusters...

yup! while i was trying to throw up. you ever try to poop and throw up at the same time? you have to aim for the little triangle hole that the toilet and your legs make! its not pretty but sometimes duty calls.

I try to move my fingers and toes but it doesn't work. what usually happens is i wait it out and i suddenly come out of it which takes about 1 min, or i can make groaning sounds while "stuck" and my girlfriend wakes me up.

I heard a myth that if you keep pressing 0 over and over, it will come close to blowing their circuits, and someone will pick up.  I've never tried it, but I've always wanted to, just to see if it's true.  :)

Another one that Mythbusters checked out - had no effect whatsoever (maybe even made it slightly worse).\n\nHave tried myself and can't say I noticed any difference.

Could be a few things..... maybe you had to strain to pass this particular movement?.... that can cause tiny fissure (cracks) in the area,..... could be haemorrhoid's - there are topical creams for this,  and treatments by doctors too,..... if it's just a tiny bit, I'd not worry much, but if it becomes an on-going thing, seek a doctor's advice.\n\nPS - if you've eaten beets recently they give a very bloody looking stool and can totally freak you out if you are not prepared for that!

YOu automatically adjust to it,unless you are in bad health..that wouldnt be a good thing to do!

This is entirely unecessary and is only done medically as part of a specific proceedure.\nAny normally functioning gut automatically moves material.\nThe non-medical process is pure quackery and can be dangerous, especially since it is administered by people who have no proper accredited medical training and qualifications.\nHave a look here:

while sitting on the floor won't help digestion I've read it will help control portion control and you aren't as prone to overeating. Here's how. When sitting on the floor you are leaning over and your legs are pulled in closer to your body causing your stomach to be compressed a little more than if you were sitting in a chair. It is just an interesting little theory I thought I'd share  :)

not always true.\nThe reason sometimes people urinate when they have a bowel movment is because of the pressure on the bladder.  The bladder doesn't put pressure on the bowel enough for someone to defecate, and there isn't always waste in the bowel to defecate.

Ok my boss got it done and my neighbor. For my boss it has suppressed his appetite as far as weight loss I can't tell. For my neighbor he said that it did suppress his appetite but not enough to help lose weight.However he use to bite his finger nails and since he did the ear stapling he doesn't. Its like acupuncture from what I understand.
