That new cast iron knee might very well cause some other lifestyle changes-——like figgering out how to get thru an airport? And you know about staying out of magnetic fields. Don’t want to get picked up by a street sweeper?
Knee is no problem in American airports.
Cast iron??? Are you sure it is not stainless steel? Titanium? If it is cast iron, forget ever getting an MRI for anything! Even being near a 1.5 Tesla could rip your leg off!
Airport? Who wants to go through an airport?
Actually, I have people hounding me to take an Alaskan cruise next year, so I might be going through an airport next year.
