Being disabled isn't a excuse for you to be lazy.
Now don't get me wrong, there are those who are disable that cannot perform any type of household duties, which is understandable.
But what about those who are able to use their hands?
If you're disabled and you are able to use your hands i recommend that you use them, by doing so you increase muscle tone and helps improve your mobility.
It really does not matter what you do even if you're just making a cuppa tea or preparing your dinner, use your arms and hands as much as possible it's a good way to help you stay independent.
