Your arms are an output device.
They depend on many input devices, to get energy.
It is possible for the input devices to fail, leaving the output devices perfectly functional, but idle.
Like I said, not all handicaps are visable.
Reign in your prejudices, man!
As I stated above; if you do not have problems using your arms, it is my opinion that pushing a manual wc is the way to go. It is good for you — gives you an opportunity to get exercise when otherwise it may not be possible. I also stated that most elderly will not be able to push a manual wc. Most have respiratory/cardiac problems.
As far as me reigning in my prejudices, I will let that comment stand. Most intelligent people will see it for what it is.
I think most of us are on the same wavelength. If a person has a legitimate disability (registered with the ADA or not) or is injured or pregnant or something, I’m all good with using the motor carts. If a person is a spry healthy 20- or 30-something who just doesn’t feel like putting forth the effort, that’s just ignorant. Why did they even go on vacation there? Sounds like the river casino boats or a Caribbean beach resort is more their speed.
