In a moment of personal crisis, how much help can you expect from a New York taxi driver? I began studying this question and answers are interesting.

One morning, I got into three different taxis and announced，“Well，it's my first day back in New York in seven years.I've been in prison.”Not a single driver replied，so I tried again.“Yeah，I shot a man in Reno.”I explained, hoping the driver would ask me why, but nobody asked.The only response came from a Ghanaian driver，“Reno? That is in Nevada？”

Taxi drivers were uniform sympathetic when I said I'd just been fired.“This is America，”a Haitian driver said.“One door is closed.Another is open.”He argued against my plan to burn down my boss' s house.A Pakistani driver even turned down a chance to profit from my loss of hope；he refused to take me to the middle of the George Washington Bridge—a $20 trip.“Why do you want to go there? Go home and relax.Don't worry.Take a new job.”

One very hot weekday in July, while wearing a red ski mask and holding a stuffed pillowcase with the word “BANK” on it, I tried calling a taxi five times outside different banks.The driver picked me up every time.My ride with a Haitian driver was typical of the superb assistance I received.

“Let's go across the park，” I said.“I just robbed the bank there.I got $25,000.”

“$25,000？” he asked.

“Yeah，you think it was wrong to take it？”

“No, man.I work 8 hours and I don't make almost $70.If I can do that，I will do it too.”

As we approached 86th and Lexington, I pointed to the Chemical Bank.

“Hey，there is another bank，”I said，“Could you wait here a minute while I go inside？”

“No，I can't wait.Pay me now.” His unwillingness may have had something to do with money—taxi drivers think the rate for waiting time is too low—but I think he wanted me to learn that even a bank robber can't expect unconditional support.

All of us, at some point, experience nights where we have difficulty falling asleep or staying asleep. The National Institute of Health estimates that one in three adults has bouts of infrequent sleeplessness or insomnia, while one in 10 sufferes from chronic insomnia. Being unable to get a good night's sleep can cause disruptions in our day?to?day life. But persistent sleeplessness can lead to physical and emotional health problems.

The body needs sleep to rejuvenate itself and rebuild the cells necessary to keep the immune system strong and the brain functioning properly. Everyone's body requires a different amount of sleep to accomplish these goals. The average amount of sleep needed by an adult is around seven or eight hours a night. However, some people can function quite well with less than that, while others need more to be at peak performance.

Sleeplessness can be caused by many different things. Most people experience sleeplessness for a short period of time due to an outside stimulus such as stress, improper diet, a poor sleeping environment or an acute medical concern such as the flu. Once the stimulus passes, the ability to sleep will usually return. Chronic sleeplessness may be caused by ongoing health concerns such as the physical pain of arthritis or the emotional pain of anxiety and depression.

Prolonged sleeplessness can have a negative effect on the way the body performs daily tasks. Those that suffer from sleepless nights may find themselves feeling drowsy or fatigued during the day. The ability to concentrate or focus on a task diminishes and you are less mentally alert. Because the body needs sleep to support a healthy immune system, those that are sleep?deprived may be more susceptible to both acute and chronic illnesses such as high blood pressure and diabetes.

Sleeplessness not only takes a toll on your physical self but also your emotional well?being. Being unable to sleep well for a few nights may only produce minor irritability. However, if sleeplessness becomes chronic, the price could be much higher in the form of anxiety, depression and possibly substance abuse. Those with chronic sleeplessness may turn to controlled substances such as sleeping pills and alcohol to aid them in their quest for a good night's sleep.

There are numerous home remedies for mild sleeplessness. Prepare your body for sleep by avoiding caffeinated drinks such as tea or coffee before bed. Don't exercise strenuously before bedtime; instead do something relaxing such as meditate or take a warm bath. Go to bed only when you feel sleepy and not because of a self?appointed bedtime.Finally, create a favorable sleeping environment by removing stimulants from your bedroom such as extra lighting or a television. If you still cannot find relief, it may be time to visit your physician for help. A sleep study will be done that can help to determine the cause of the sleeplessness and possible solutions.
