To tell the tooth, I don't know whether its worse to have a cavity in my wallet or to have all my wisdom removed!

The nerve signal, or action potential, is a coordinated movement of sodium and potassium ions across the nerve cell membrane. Here’s how it works:
1. As we discussed, the inside of the cell is slightly negatively charged (resting membrane potential of -70 to -80 mV).
2. A disturbance (mechanical, electrical, or sometimes chemical) causes a few sodium channels in a small portion of the membrane to open.
3. Sodium ions enter the cell through the open sodium channels. The positive charge that they carry makes the inside of the cell slightly less negative (depolarizes the cell).
4. When the depolarization reaches a certain threshold value, many more sodium channels in that area open. More sodium flows in and triggers an action potential. The inflow of sodium ions reverses the membrane potential in that area (making it positive inside and negative outside — the electrical potential goes to about +40 mV inside)
Use biofeedback. Biofeedback is a way to strengthen and coordinate the muscles and has helped some people with incontinence. Special computer equipment measures muscle contractions while you do exercises—called Kegels—to strengthen the rectum and improve rectal sensation. These exercises work muscles in the pelvic floor, including those involved in controlling stool. Computer feedback about how the muscles are working shows whether you’re doing the exercises correctly and whether the muscles are getting stronger. Whether biofeedback will work for you depends on the cause of your fecal incontinence, how severe the muscle damage is, and your ability to do the exercises.
What I am trying to say is when we are seriously in need of a toilet, how can we control our bowel movements until reaching the toilet?Don't think about it
You may have noticed that mosquitoes often seem to hover around a person's head. This generally happens if the person has dark hair. To combat this, you could consider wearing a cotton cap in a light shade on your head.Mosquitoes are attracted to the colour black, so if you are going to be outdoors and expect to be exposed to mosquitoes, opt for a lighter colour.http://www.indiaparenting.com/health/324_2126/natural-mosquito-repellents.html
Can it be stopped?You know how to get constipation? [xx(]
Certain kinds of poisons, like the secretion of a Japanese blowfish, can put someone in a comatose state and make them appear dead even to a doctor. Narcisse had ingested some poison like this and when he slipped into his death-like state was buried. Then someone came and dug him up. Upon awakening he was giving doses of a “zombie powder” which contained the drug Datura stramonium. The drug puts the user in an emotionless, trance-like state, but the user can still perform menial tasks. In Narcisse’s case he was used as slave labor on a sugar plantation. He was a zombie-slave for 18 years.
