My mum is 94. She’s completely immobile now, and needs a hoist to get her into and out of bed. But before this, she had great difficulty getting into or out of a car, or lifting her foot to go up one small step, and she could only walk a few steps if she had her walker. Mainly, if she went out, she was in a wheelchair. Considering all of this, I think the Queen is having mobility issues. It appears she doesn’t want to be seen in a wheelchair, but even if she was okay with that, as I said, getting into or out of a car has its own difficulties.
