Why don't we fall apart?

"Things" don't fall apart because the "things" are held together by atoms . Bonds are formed which make the "things" stable. The gravitation force plays a substantial role in this subject. The things when are bonded need energy and when they need to be disassociated they release energy thus evolving the conservation of mass law. "Energy can neither be produced nor destroyed, only transferred from one form to the other.

So the conclusion sthat atoms are made out of quarks and leptons which help the "things' not fall apart!
