When you clicked on the Nye Labs web site to read this you used your bones and muscles.
Without them you cant click surf or even sigh.
Bones and muscles work together or you arent going anywhere.
Muscles always pull even when you push on something like a door somewhere in your body your arm and leg muscles are in tension.
They are all attached to bones and those bones are pushing theyre in compression.
By pulling on bones you can breathe talk and move all over the world.
Your bones support your weight like beams of steel or wood.
Theyre stiff and strong.
Rigid as they might seem though they do flex.
And if you bang one hard enough it swells up.
You have a lump.
Thats because bones are full of blood vessels.
Bones are not solid like rocks or skeletons in a dinosaur museum.
Bones flex and grow.
In fact putting healthy amounts of stress on your bones is good for them.
