You can do everything "correct" and be disabled. Most of us will become disabled at some point if we are lucky enough to live that long.
Eating nothing but free range organic lentils and exercising or whatever the wellness industry says this week won't spare you.
Pay attention to disability issues.
Demand this from politicians.
Disability should not mean food and housing insecurity. It's not even saving money to set up this cruel system, so politicians are telling you lies. Fight back.
