People, most likely in their mid 50s, suffer from Osteoarthritis. But not all aging people have this kind of a condition. There are people in their nineties who are as active like when they were still young.

In fact, there is nothing to be surprise of if we encounter someone we knew that he or she has Osteoarthritis. Osteoarthritis is in deed a very common disease to people above 50 years of age. It is nothing unusual.
