You probably think of death when you think about skeletons. Maybe you think that skeletons are like scaffolding, holding everything in the body in place. The truth is bones are a lot more. They're alive.

You probably think of death when you think about skeletons. Or maybe you think that skeletons are like scaffolding, holding everything in the body in place, and the bones are like metal bars. True but bones are also very much alive. They aren't just some solid material like metal, they are alive with cells. Human bones have three layers. The smooth, hard outer layer is cortical bone. Beneath this layer are many layers of cancellous bone. Cancellous bone looks kinda like a sponge. Although not quite as hard as cortical bone, it's still pretty strong. The third and innermost layer is the bone marrow. Bone marrow is like a thick jelly, and its job is to produce blood cells. So, as you can see, bones aren't only alive, they're responsible for keeping you alive as much as the heart or the brain!

What Do Bones Do?

1Bones make blood cells.

1Bones are the framework for your body.

How Many Bones?

Humans are born with 300 bones, but adults only have 206 bones. So what gives? Some of the 300 original bones in a baby are made of regular bone and some are made of a material called cartilage. Cartilage is soft and flexible to start, but over the years the cartilage grows and slowly hardens into bone. Also, some bones fuse together. All of this is part of the normal growth process.

Some time between the ages of 17 and 21, this growth process ends and your bones are as big as they're going to get. And like magic, you end up with 94 fewer bones than you started with.

Bits of Bones

1More than half of the body's 206 bones are in the hands and feet.

1The skull is composed of 30 different bones.

1The smallest bone in the body is the stirrup bone inside the eardrum. It is less an inch long.

1The largest bone in the body is the femur which is the leg bone that runs from the hip to the top of the kneecap (patella.)

1Everyone's heard of the funny bone, but did you know that humerus is the real name of the long bone that runs from your elbow to your shoulder.

I think you can not be sure he likes you. take me as an example theres this girl in my class who i talk to everyday. Now i see her as a sister and i have and will go to lengths just to make sure shes okay and her boyfriend doesnt hurt her. This might be what is happening in your situation so i advice that you wait a bit longer because him loooking at you may mean that he likes you and is waiting for the right time to tell you. Meanwhile you can get closer to him and flirt once in a while to asure that him you also like him (that is if he isnt sure). And dont worry if he doesnt like you back its better to have a friend who cares about you than a boyfriend who doesnt like you that much and is dreaming about someone else.

What part of it are you scared of? Is it eating in public and around other people, or just eating in general?  What it might be, if it's eating in public you don't like, is social anxiety, or social phobia. You should ask your doctor to check, because if it is, they can offer you ways to help. For instance, they might recommend therapists or group sessions to help ease your fear.  Even if it's just a phobia or, in unlikelier circumstances, an eating disorder, you should still go to your doctor or a therapist so you can try to overcome it. Try doing things that calm you down before these situations as well, like exercise, reading or listening to music (I'm not sure what relaxes you but sometimes these help). Also, you should try to slowly get used to the situations. So don't force yourself to eat straight away when you're out, but slowly start doing so whenever your comfortable with doing so. Unlike your mum wants, you can't just "stop" being scared because that's not how it works.  But right now, please don't force yourself into any of these situations. It's not good for your mental health to be forced to face a phobia of yours often.

Dear Dish-It, Within the last few years I have felt a bit sick and shaky when we go out to eat. It's not so bad when it's a carvery lunch or something at a pub, but settling down for a chocolate brownie and a milkshake shakes me up. Don't get me wrong, I love going out with Mum, but it's just sitting down and taking a bite. I want to chuck it in the bin. I love eating brownies and stuff at home and I'm pretty healthy. But I refuse to go to the town before lunch in fear. Mum told me I got to stop this or I'm going to develop a terrible phobia.  Please help! ElfyKathy, worried
