$\huge\mathcal{\fcolorbox{lime}{black}{\blue{AnsweR :-}}}$

Some joints like shoulder joint, knee joint need to be held firmly in position to be well-lubricated. Such joints contain a lubricating fluid called synovial fluid, which serves as a cushion between the bones and removes friction during movements. As we age, the joint movement becomes stiffer and less flexible because the amount of lubricating fluid inside the joints decreases and the cartilage becomes thinner. Ligaments also tend to shorten and lose some flexibility, making the joints feel stiff.
