I think most of you do not consider how much usclimbing stairs pushaffect your kneecaps.

You press your knuckles while climbing the stairs.

Your knuckles is 👊🏾. It makes sounds when you press it.

For your knees, there's kneecap and knee joint. I searched online and you should be referring to the kneecap. The kneecap is the part you kneel on.

When you move up the stairs, 3 bones are involved — thigh bone, tibia and the kneecap. These bones slide over each other but there's cartilage that prevents friction. When this cartilage reduces, that's when there's pain while using the knee.

Knee joint is the one that helps to move your leg to the kneeling position.

Maybe going up 3 or 4 storiesairs can be fine, bu no more than 5 storieairs.

In Nigeria, we call buildings with stairs — story building, but I don't know if that's correct.

The more storieairs you climb, the more your knee jointcap might wear out.

People should diversify withe exercises like jogging, lifting weight etc.
