Health is half about management, but still, sometimes due to genetic factors.

It's really sad if there's a congenital weakness, whether it's the teeth or the bones.

I envy people who are naturally born with strong muscles and bones from the moment they are born, like thisㅎㅎ

Still, eating minerals and protein to build muscle helps a bit, but since I was young...

I've been worried a lot lately because my shoulder joint isn't in good condition and my bones are weak, haha.

Degenerative conditions don't necessarily improve just by exercising a lot, and anyway, worries about health never seem to end.
