cool. This is called spaghetification. Your feet are being pulled slightly more towards earth than your head, because they're closer to it. The same thing happens when aproaching a black hole, though, because of it's intese gravity, It's way more intsnse, your feet will be closer than your head and stretch out, making them get even closer to the black hole in relation to your head, stretching them out even more and so on. It ends with your atoms being torn appart.
