People are often not aware of how their ability to function far exceeds some other people who are not so fortunate.

To describe a lifestyle of "surviving on black beans and rice" and riding your bike around, implies that you maintained a functioning household and kitchen with paid, active utilities; you were able to clean the room, vessels, appliances and utensils on a regular basis; you did pest control as necessary, and you were able to accomplish basic cooking tasks 2-3 times a day, every day.

Accomplishing all these tasks well enough to survive, feed yourself without hazard, and not become overrun with cockroaches is a sure sign of baseline mental capacity and cognitive function. Again, there are lots of poor people who were homeless, or grew up in dysfunctional households, or are on the brink of homelessness, and struggle with mental illness that militates against them "surviving on black beans and rice" day by day.

So I congratulate anyone who can accomplish these seemingly-trivial tasks. You deserve a pat on the back for sure!
