Same here. And I'm, um, well, past 60.

This is a Biggus Dealus. Also, as below, you need to stay out of the back seat.

That puts more pressure on your kneecaps and ACL, and then when you slam something, it can rally hurt you. If you stay out of the backseat, you shouldn't have much trouble with your knees.

Yeah, the zipper line is the one people see. It is possible to ski the zipper smoothly, but it requires accurate balance and effective movements. WC emphasizes flamboyance and at least appears to include significant impact. Sounds like it, too. I prefer the Nelson Carmichael silver medal run from a number (20?? More?) years ago. His skis stayed on the ground. He was quiet and smooth.

Yes. Smooth it out, suck it up and then extend, stay out of the back seat, smear, learn how to slow it down smoothly, even in intense, choppy bumps. It can be done, but it requires discipline. Learn to see other lines besides the zipper.
Balance is huge to minimize stress on the knees. Just because you didn't fall down doesn't mean you're in balance.
I'm past 60. I've had a broken back. I earn my living in front of a computer. I ski bumps. It can be done.
