Studies show that regular sex (with all due precautions taken) provides a host of surprising health benefits.

Sex is good for adults. Indulging on a regular basis—at least once a week—is even better. Research links sex (with all safer-sex precautions taken) to an astonishing array of physiological benefits, from longevity to pain relief. Many studies don't address whether the health bonus comes from the act itself or from the corresponding emotional intimacy, but the bottom line is that getting physical has some great side effects—especially for women. Here are six ways that sex boosts your health:

1. It Fights Colds and Flu. Sexual intercourse once or twice a week raises the body's level of the immune-boosting antibody immunoglobin A by a third, according to research at Wilkes University in Pennsylvania.

2. It's a Beauty Treatment. In a study at the Royal Edinburgh Hospital in Scotland, a panel of judges viewed participants through a one-way mirror and guessed their ages. Those who looked seven to 12 years younger than their age (labeled "superyoung") were also enjoying lots of sex—four times a week, on average. OK, maybe they were having so much fun because they looked young. But it's likely the sex was helping, researchers say. One reason is that it raises a woman's estrogen level, which helps make hair shiny and skin supple.

4. Yes, Honey, I Have a Headache. For a woman a migraine might actually be a reason for making love rather than avoiding intercourse: the increase in endorphins and corticosteroids during arousal and orgasm is analgesic.

5. It Promotes Regular Menstrual Cycles. A series of studies by behavioral endocrinologist Winnifred Cutler and colleagues at Columbia and Stanford universities found that women who have intercourse at least weekly (except during their period) cycle more regularly than abstainers or the sporadically active. (Related research found that lesbian lovemaking also smoothes out menstrual cycles.) Cutler argues that intimacy is essential, not orgasms: "Regular exposure to a loving partner has extraordinary effects on health and well-being."

However, I generally find myself leaving the strip club with an empty wallet. Any business that can get you to spend all of your money is a good one to be in.

But while walking out of a club one evening, I realized that a big reason they have such a good business is because strippers are such great salespeople. It is not simply due to the fact that they are selling to stupid, horny men like myself, but because they use a lot of highly effective sales and marketing techniques.

You too can achieve great success by applying sales and marketing techniques of strippers. Here are 10 sales and marketing techniques I have learned from strippers:

Sales Technique #1 - Give them something for nothing
One of the first things a stripper will do is come up to you and flirt with you. She will likely sit on your lap or do something to raise your excitement level. For this, you have to do nothing. But you do get a sample of the service and if it is a good one, your chances of buying the service increases. This also applies to the dances they do on the stage.

Sales Technique #2 - Understand your customers
Strippers get to know your their customers by asking questions. This allows them to develop a rapport and tailor the sales pitch…

Sales Technique #3 - Tailor the Sales Pitch
Strippers will try different sales pitches to different people based on what she thinks they like. “I like to get dirty” or “Have you seen my great ass?” or “My tits are real”. Each pitch may be the one thing that converts the potential customer into a buyer (pointing out a tight ass works well for me). And she revises her pitch based on experience.

Sales Technique #4 - Make sure you are selling a great product/service
She knows she has to have a great product. If she put on 30 pounds or hadn’t showered for the past 4 days, she would likely not get as many customers. Regardless of how great of a salesperson you are, you can’t do much with a crappy product/service.

Sales Technique #5 - Provide Good Customer Service
She will make sure you are happy on your first dance or she won’t get repeat business or won’t be able to do what she ultimately set out to do…Upsell.

Sales Technique #6 - Upsell
She sells the customer on a relatively cheap service, a lapdance, but then markets her other services to them. She tries to get them to the “champagne room” and sell an upgraded service, which is where the money is at. However, without the first sale, she would never get the larger sale. Customer acquisition is tough, once she does it, she needs to get as much business as she can.

Sales Technique #7 - Closing Techniques
She will use a variety of closing techniques to get you to buy her services. There are a variety of closing techniques, but two popular ones used by strippers are the compliment close (usually flirting with you) and companion close (getting your buddies to push you into closing the deal).

Sales Technique #8 - Target your audience
Strippers market to individuals that are interested in her service. First, she works in a strip club where guys go specifically for her service, that is obvious. But she also knows which guys to go after within a group or which groups will likely spend the most money. Spending time with cheap-asses only wanting to pay a dollar for a dance will not be a wise use of he precious time.

Sales Technique #9 - Persistence
Even though the audience is qualified, she knows she will get rejections. Even so, she will go up to every guy and ask if they need a lap dance. She also knows that the more guys she asks, the more yes’es she will get.

Sales Technique #10 - Branding
I don’t know any strippers that are named Ethel, Mildred or Agnus. Instead, you will get the pleasure to do business with Cookie, Destiny, Candy, or Raven.
