1. Famous poets and writers have claimed for centuries that love stems from powerful emotions. 2.
However, research has shown that feelings of love are at least in part influenced by various
chemicals in the brain. 3. One group of chemicals that is just beginning to be understood is the
pheromones-substances that promote sexual attraction in the opposite sex. 4. Experiments show
that males release a chemical in their sweat that has been shown to be highly appealing to women-
particularly during ovulation. 5. Similarly, women produce their own pheromones that draw men's
interest-one actually can raise the level of testosterone in a man's bloodstream. 6. In addition to
pheromones, another chemical, phenylethylamine (PEA), plays a crucial role in helping people fall"in
love." 7. Related closely to the addictive stimulant drugs called amphetamines, PEA actually causes
people to feel a high from their relationship. 8. The "heart-throbbing" sensations new lovers describe
and the feelings of excitement and infatuation that are part of new relationships are directly
attributed to this chemical. 9. As with many addictive drugs, eventually the body builds up a
tolerance to PEA and the strong feelings begin to wear off, usually within two years. 10. This
explains why infatuation cannot last forever. 11. A third group of chemicals-endorphins-appears to
be at work in long-term relationships. 12. Endorphins are the body's natural pain relievers. 13. In
addition, they produce a sense of security, tranquility, and calm. 14. During physical intimacy,
endorphins are released into the bloodstream, creating the feeling of satisfaction and security
common to long-term successful relationships.

Voluntourism: an opportunity too good to be true a speech to the student body of evergreen high [1] picture this: it's spring break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. there's also people in need, so you decide to blend your vacation with volunteering. volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and people at the same time. however, this "volunteer plus travel" experience can actually harm local communities. while many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference. [2] most would agree that volunteering in general is a worthy use of time. however, what if you found out the children you are "" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? dale rolfe, a supporter of ethical voluntourism, explains the shocking reality that "animal sanctuaries and orphanages are often manufactured for the voluntourist…encouraging a cycle of exploiting the very animals and children the volunteers are trying to ." [3] proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. with voluntourism, however, participants often pursue experiences that are all about them. for example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (schulten). or, they arrive to teach english but instead take selfies with the locals. one world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (carlos). the voluntour experience is a mirage. the voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved. [4] if you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. you can volunteer in your local community. give an hour every week to your town's animal rescue. serve monthly dinners to the homeless. be a reliable, positive influence on a child who needs a mentor. studies show that volunteering and forming lasting relationships with those you has a positive impact on your physical and emotional health. in fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (michaels). [5] there is another reason to look into alternatives to voluntourism. did you know the average "voluntour" travel package costs $3,400 (rolfe)? could that travel money be better spent? if the world's citizens are your passion, it could go to an international organization. if you care about education, your funds can be used to buy books for students in faraway lands. if you want villagers to have clean water, contribute funds to local efforts to dig wells. if you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best them after you've returned home. but do not voluntour. [6] in reality, there are better ways to make a difference. voluntourism might appear to be an adventure that blends travel and others, but it does little except provide a costly, superficial experience that might actually do more harm than good. so, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. whatever you do, don't turn someone else's hardship into your vacation. which paragraphs address the counterclaim of the argument? paragraphs 1 and 6 paragraphs 2 and 3 paragraphs 3 and 4 paragraphs 4 and 5
