It is wrong to assume that your first answer is more likely the better answer.  60 studies consistently showed that going with your initial response or answer is not a good strategy if you start second guessing yourself.  Typically, people who changed their answers more when they were unsure scored higher.

Apparently thinking with your brain is better than going with your gut.  Wild.

Cell phones cannot cause cancer.  Only x-rays, UV light, and gamma rays are strong enough to break the covalent chemical bonds in your body.

But if you use a cell phone will getting x-rayed, or tanning, or floating around near a quasar, yeah, I guess you could get cancer.

Etymologically “hamstring” comes from “ham” (the fat behind the knee) and “string” (a tendon).    It’s all highly medical, science jargon.  I can barely understand it.

Lamarckism or Lamarckian inheritance is the idea that an organism can pass on traits that have been acquired during its life to its offspring.   This idea generally isn’t too popular anymore in terms of genetic evolution.  I am really bored.

To conserve oxygen, blue whales can slow their heart rate down to 4 beats per minute.

Why don’t they just breathe?  Are they really that busy?

Taste buds are not only on your tongue, but also on the roof of your mouth and the top of your throat.

Sometimes I press my tongue to the roof of my mouth so my taste buds can taste each other.

Unlike nocturnal creatures, which are active at night, or diurnal creatures, which are active during the day, crepuscular creatures are active at dawn and at dusk.  Ferrets, dogs, cats, rabbits, and old people are all crepuscular.

In addition to striped fur, tigers also have striped skin.

This was the hardest fact of the year for me.

Have you ever tried to shave a tiger?

Until the seventeenth century, hysteria referred to a medical condition in females that was thought to be caused by disturbances of the uterus.  In Greek, hystera means “uterus.”

I think it still exists.

It is rare for a Venus flytrap to catch more than three prey in its lifetime.

I’ve been living in fear for nothing!

“Arctic” comes from the Greek arktos (“bear”), due to the northern status of the the Big Dipper constellation (aka the Big Bear).

I wish science was still based on animism and astrology!  I could be such a good scientist.

8 out of every 10 people killed by lightning are men.

Guys rule!!!!!

In the early 1800s, the Fugate family (better known as the “Blue” Fugates) lived in the hills of Kentucky… and many of them were blue.  Some of the family members possessed a hereditary genetic error called methemoglobinemia, which causes the blood to have reduced oxygen levels.  With lower oxygen levels, arterial blood that is typically red is instead brown.  In Caucasians, brown blood gives the skin a bluish hue.

I doubt the Fugates, though blue, even make it into the top 10 freakiest hereditary mutations to come out of the hills of Kentucky.

The earth is about 4.6 billion years old.  The oldest known fossils are approximately 3.5 billion years old.  Homo sapiens have existed for about 100,000 years. 

Yet, 2012 is the end of it all.  We are quite special.

I hope my fossil will last a few billion years.  If I ever die, I want someone to tape a bunch of animal bones to my bones, so when I’m fossilized I will totally freak out the future civilizations!

I tried to make it sound less morbid by emphasizing if I die. 

The caruncula is the tiny little pink thing in the corner of your eye. 

It’s probably my sexiest body part.
