You had better learn quickly. Your body’s joints are amongst your most prized assets, along with your heart, lungs and brain. Without your heart, you would not be able to regulate blood to all vital parts of the body. Without your lungs, you would not be able to breathe and pump vital oxygen to all organs of the body. And without the use of your joints, you would not be able to move freely and in the supple manner required or desired. Never mind moving like a robot, you simply would not be able to move at all.
And even if you could, it could be a painful, if not, stiff process. These are things you can still do when you are still relatively young. And the longer you are able to take care of your joints and all other vital parts, the longer you will be able to use them. Right into old age. But if only it were that simple. Whether it has something to do with the regular motions you were always required to perform, or whether it has something to do with hereditary characteristics, you could still end up with the stiffness and/or pain.
Nothing more unpleasant or distressing as that. And so it goes that inevitably, the aged man or woman reaches the point where he or she has to face up to joint replacement in Mount Pleasant. But rest assured that this is never going to be something of a death sentence. Medical science and its related technologies have come quite a long way. There is much to look forward to in terms of being able to be comfortably mobile for however many years you still have left on this good earth.
