Not so much age, but mileage. I've had both hips replaced in the last two years, the right side March of 22, (the worst of the two), and the left March of this year.
Turned out to be an injury I didn't know I had from boot camp.
Good thing is that I'm repaired, but there are a few things I can't do anymore. Like running, squatting, and a few other things are iffy......
I'll replace running with a bicycle, leg work will have to be a careful choosing. The biggest restriction is the lack of range of movement with the new hardware. But, I've been where it's worse, and I'm happy being better, even with the restrictions.
Hell, I'm only 45............

My matching set of Titanium hardware, just shy of Forty thousand dollars worth of replacement joints.
