Do you know anybody in a wheelchair? I do not.
My grandmother used to have a chair, a heavy duty hospital type.  I understand they come in a range of formats for each person's needs.
That's good to know. I wonder how much the technology has advanced. Some of the wheelchairs re fairly sophisticated .
Yes, but they are not as sophisticated as a Ford  F Series truck.  The F series are heavy duty trucks that have been manufactured since 1948.
