Because, we don't feel it because we were born with it but thousands of units of force are beating on our heads through gravity and in space since that gravity is not present it takes less force from your muscles to move around

Weaken bones can result from an excess secretion by?
calcium leaking out
What problems can be caused by an astronauts bones getting thinner?
When an astronaut goes to space, the lack of gravity in the capsule or the space station will make his bones and joints very weak. A period of 2-hour exercise is required every day so that his bones will not shatter when he returns to Earth. Technically the astronauts' bones will not get thinner, but instead weaker. Problems like osteoporosis can be caused if the astronaut stays in space for extended periods of time.
Can radium be poisonous?
Not chemically but yes radioactively.When ingested radium substitutes for calcium in the bones. Its intense radiation first kills the osteoblasts (bone forming cells) causing bones to weaken and even crumble away, then it kills the bone marrow causing both anemia and immune system failure.

How do a well-balanced diet and a weight-bearing exercise help keep bones strong?
The diet will ensure the elements you need to make and repair bones are present in your body as needed. Weight bearing stresses on bones causes electricity in the bones to be generated these micro electric currents stimulate the bones to strengthen in response. Thus in space where there is no gravity to cause weight, the bones of astronauts weaken (despite a good diet) and they have to exercise against springs to cause stresses in their bones.
What are bone disorder drugs?
