What if gravity is killing us ?

supposedly, when earth lines up with some black hole whatsit, the gravity increases, but this happens all the time, every year? 2? 3? anyway, our body isnt being gently pressed on the ground its aggresivly forced to ground by gravity, so, your organs will be feeling preasure right? pushed down, when you get old everything goes down..? including your organs? so if this gravity thing doesnt effect us, then wheres the giants? theres bones but no sign of live ones, theres the tall gene so thats proof too right? everything goes down in size over time because the force of gravity is increasing? people die younger these days too, and the "world leaders" ( for whom i saw no vote system ) are all standing around taking pictures for magazines and kissing chocolate doughnuts for trade deals.
