Why do we need fingernails?

Screen Shot 2014-12-01 at 3.44.12 PM

Do we need fingernails to get them painted, to make our rings look good? According to John Hawks, “a biological anthropologist at the University of Wisconsin-Madison. Fingernails are one of the features that distinguish primates, including humans, from other mammals.

They are essentially flattened forms of claws.? Is it because its useful to scratch, peel fruit, open jars, undo nots and shoelaces? It would be interesting if there was a study done that should how people live with fingernails and how people live without fingernails.

I believe their lifestyles would be almost the same. Our nails are made out of a protein called keratin. Maybe this gives our body protein? Is it unknown why we have fingernails? Where do fingernails come from? Do they serve as tools for us and thats it? In my conclusion, it seems as if fingernails are just there and serve as little tools for us to help do little things, that you would never think of is the reason we have fingernails and the purposes they serve.




Television and Children

Screen Shot 2014-12-01 at 12.44.13 PM

A very highly talked about topic in the US is how much television a child matches or really how bad is television for young kids. Does it effect the development of their attention disorders as they grow to become adolescences and eventually adults? The first two years of a Childs life are critical times for brain development. Electronics and especially TV can interfere with the way the brain develops.

As kids get older, too much TV can effect activities such as being physically active, reading, studying, experiencing social scenes with friends and family. It must be hard as a parent to try and help your kid avoid TV if you watch it yourself.  In some households, the TV is just on even without anyone watching. Some parents buy videos and shows that they think can make their kids smarter. But why not just buy a board game? Or a kids book or game?

According to, “Researchers from the University of Sydney report a link between total screen time and retinal artery width in children. Kids with lots of screen time were found to have narrow artery in their eyes, which may indicate heart risk.”

In conclusion, i believe that tv at a young age is not beneficial to help a brain develop. I do not think kid shows are even positive for children. The types of kids shows there are today are becoming more and more harmful to a child.


Is not eating Dairy good for you?

Screen Shot 2014-12-01 at 12.17.46 PM

You may hear your Doctor tell you that you need to eat dairy everyday, or your nutritionist may tell you to eat yogurt for breakfast instead of oatmeal. Few people are willing to talk about dairy and tell the truth about it.  For example, my best friends mom used to eat yogurt for  breakfast, and would put cheese on her sandwiches for lunch. She started to feel extremely blooded. She eventually stopped eating yogurt for breakfast, cut out milk in coffee, and absolutely no cheese and lost 10 pounds extremely fast and had zero blooding. I told my mom about it and she started doing the same thing. My mom saw the same results as my friends mom.

According to the Huffington post article,, milk is high in saturated fat and switching to skim milk will not do the trick. “A large Swedish study also discovered a link between fattier milk and a lower risk of weight gain in adult women (normal-weight women who drank one or more cups a day of whole milk had a significantly lower chance of gaining weight than those who drank reduced-fat milk).” There are however dairy replacements. Such as soy milk. There are no replacements for ice cream but if you are a milk nut, then soy milk, coconut milk, rice milk, and almond milk, are an options for you.

In conclusion, I believe that cutting out dairy from your diet will allow you to become less blooded and you will loose weight without even trying .

Everyday Foods that cause cancer

Screen Shot 2014-11-14 at 8.53.08 AMThis probably does not come to mind everyday whether or not the food you are eating contains carcinogens, however around 1.5 million people were diagnosed last year with any sort of cancer.  According to, there are 16 everyday foods that can cause cancer.

1. Microwave Popcorn: The inside of the bags are lined with perfluorooctanoic acid which is a chemical toxin. According to scientific studies done, perfluorooctanoic is linked to women in a infertility type of way. Another chemical that is on the popcorn itself is diacetyl.

2. Non- Organic fruits: When you go to a food store, have you ever questioned whether or not to buy organic or non- organic foods? When i go with my family we can never tell the difference between organic and non-organic foods when we cook them so usually we buy non-organic. In 2009, a study was done that found that when pregnant women drink water with atrazine in it, their baby weights less. Which fruit do you think is the worst contaminated one? Apples are the worst. 98 percent of apples have pesticides.

3. Canned Tomatoes:  It is not unknown that most canned foods are unhealthy. Personally, i try not to eat canned foods because i know how processed they are, but I did not know they were this bad. The cans are lined with the chemical bisphenol.  Tomatoes have a high acidity which make them more dangerous.

4.Processed Meats: When I think of processed meats I think of stuff that contains a ton of sodium.  The salts that are used to make these meats are extremely damaging to health. Processed meats contain chemicals, and sodium nitrates.

5.Potato chips: I know potato chips are extremely unhealthy but I also know how good they are. They are high in fat and calories which obviously causes weight gain. They have artificial flavors, many preservatives, and the material which makes them crispy called acrylamide which is found in cigarettes.

6.Artificial sweeteners:  Most use artificial sweeteners in coffee, teas, baked goods etc. Aspartame has been found in many artificial sweeteners. These sweeteners prohibit the human body to monitor its daily calorie consumption.

7. Alcohol: Have you ever heard of the freshman 15? Most of the weight gained comes from alcohol, not just bad dining hall food . Late night eating is caused from alcohol. It is the second leading cause of cancer.

In a sense, anything can cause cancer. The foods listed above are some everyday foods that can cause cancer which you may have not known. It is shocking that scientists have not found ways to prevent these foods from causing cancer or using different chemicals and ingredients.

Why is junk food so addictive?

Screen Shot 2014-10-12 at 8.38.44 PM

We eat it even though we know it is bad for us. Why does this happen? Companies design the foods this way to be addictive.  Because more and more people are starting to watch what they eat and the ingredients in the food they eat, companies are going to start telling people that these foods are okay to eat. Some people believe that junk food addictions start from the womb.

According to, that “sugar snacks activate areas of brain that are also stimulated by hard drugs such as cocaine and heroin.

Studies have shown and it is obvious that junk food companies spend billions of dollars on marketing for their products and figuring out what ingredients to put i0n the food so buyers will become addicted and continue to buy that product. According to studies, we are addicted to junk food because our bodies cannot handle the sugar, fat, and salt in the product.

In conclusion, I think that these companies put so much money and time into thinking how they can make their products addictive. The sugars, salts, and fats are too much for our bodies to handle at one time. These foods will continue to be addictive until companies stop putting these chemicals and money into marketing for them.

Is running on a treadmill just as beneficial or more beneficial than running outside? Or is one more harmful then the other? Some scientific research has show that running on the treadmill is basically the same as running outside. Actually, there are some workouts that can be done better on a treadmill than outside.

Some benefits of running on a treadmill vs outdoors:

1. Can run when the weather is bad

Is sweating bad or good for the health?


Screen Shot 2014-10-05 at 2.07.29 PMDo you ever get concerned when you work out really hard and do not sweat? Or when you sweat too much? I believe sweating is a positive thing for the human body and health. According to, sweating maintains proper temperature, expels toxins, kills viruses and bacteria, and cleans pores.  Along with sweat cleaning pores to eliminate acne, sweating can also cause acne if you do not have good hygiene while allowing yourself to sweat. During workouts, sweating allows the body to maintain certain temperatures so your body does not overheat.

Sitting in a sauna obviously allows the body to produce a lot of sweat in a short period of time. That is one easy way to allow your body to sweat. Sitting in a sauna has positive side effects for the body similarly to how sweating while exercise does. It reduces cold and flu, body detox, skin cleansing, relaxation. Another way to sweat while relaxing is hot yoga. I am absolutely terrible at yoga, but when I want to sweater and feel like i am exercising, I always resort to hot yoga.

In conclusion, I think sweating is very good for the health. According to facts and studies done, there is nothing significant that shows sweating is bad for the body.

Pros and Cons of an E Hookah

Screen Shot 2014-09-17 at 1.57.18 PM

E Hookahs are NOT bad. There is no tar, no tabaccoo, they are rechargeable, disposable, no need to clean, no lighting coals and all around easier to travel with. Some negative things about an Ehookah is that they are more expensive. Basically that is it. E hookahs are good for people who are trying to quit smoking. Eventually, I believe this technology will become better and more and more flavors and designs will start to happen. According to, ” a hookah pen is a device that delivers nicotine as a vapor to the user. ” This however, is not the same as a hookah. A real hookah uses a special type of tabaccoo.

Is Exercise good for the brain?


For most of my life, I have been physically active. Whether its going to the gym, or playing sports, or even going for a walk, I have always done something. In the past years, more and more studies have shown and proved that physical activity is not only good for your body’s health but also for the sharpness of your brain. Physical exercise affects the body by increasing heart rate, releasing endorphins, and completely clears the mind. According to article, ” By the end of the study, the researches found that not only were the participants’ body measurements all improved– they also did better on the tests of cognitive functioning. ” In many schools, it has been proven that when students exercise before tests or the start of the day, they do better. A lot of schools tested students before standardized tests and the students who worked out before tended to have an overall better score than the students who were not physically active. Even walking three times a week can have a positive effect on the brain. From personal experience, I can confidently say that physical exercise has helped me in school and many other ways.








Initial Blog Post

Hi everyone, my name is Jess Herman and I am from a town 15 minutes outside of Philadelphia called Penn Valley. I am enrolled in the college of Division Of Undergraduate studies , but I want to major in business marketing.  Throughout high school I never enjoyed biology, chemistry, and physics .  They were very challenging for me and most of the time boring. Those three classes closed my mind about becoming a science major.I realized science does not excite me in anyway.  When I was enrolling in courses for my first semester , i realized I needed a science class.  Because science is not for me,  was very Fortunate when I found this class. I heard great things about this class and I can’t wait to experience them myself. During my time here as a college student, I want to travel abroad to Florence, Italy.
