Be like my 90 year old mother who has no cartilage left in her knees and, at 90, not interested in the surgery. Get yourself some wheels! She has a motorized tricycle called Zoome- ah, here it is. This bad boy can do 30 km/hr, she zips across the parking lot into the clubhouse/dining room building in this, I have to run to catch up (she's used to going over on her own, I am slowing her down...).
There are other ones that are just bascially a scooter with a seat (but her balance is not that great-I got her a portable one but was too unstable, gave it to my niece).
And, when you're older, you have the prerogative to run anyone over who gets in your way...
