The human body is an amazing thing. It is capable of creating life, surviving horrible diseases and accidents, and tasting all kinds of good (and equally bad) food). But human bodies are also susceptible to great tragedies, from freak accidents to medical mysteries. Understanding your body and how it works is vital to not only surviving, but also to live longer.
 
 “A person who is not very active can start by making small changes, such as replacing soft drinks with water and adding a 10-minute walk to a daily routine,” Carly Schuna writes for Livestrong.org.
 
And understanding your body and the benefits of good health are vital for thriving communities as well. “Better health is central to human happiness and well-being,” the World Health Organization’s website reports. “It also makes an important contribution to economic progress, as healthy populations live longer, are more productive, and save more.”
 
So how much do you know about your body? What you don’t know will surprise you, like how 50 percent of your hand’s strength lives in your little finger. Well, if you want to know about your body (and why wouldn’t you?), we have you covered.
 
Here are 50 facts about your body that you probably aren’t aware of, but should be:
 
1) Twenty-five percent of bones in an adult are in the foot. Even more of a reason to get those sensible shoes.
2) The body’s largest muscle is the gluteus maximus a.k.a. your booty a.k.a. your twerking muscle.
3) You will likely eat 100,000 pounds of food in your lifetime. Set a goal to make 25,000 pounds of that food pizza.
4) The only part of your body with zero blood flow is the cornea of eye. It only requires oxygen.
5) If you think you have big ears or a big nose, there’s a reason for that: both parts of your body never stop growing.
6) More than 278 different types of bacteria are exchanged when two people kiss. 95 percent of them aren’t harmful.
