Back in those days .. People suffered and endured all kinds of health related hardships .. And still continued to do their duties. If they couldn't it could plausibly mean their family would starve or freeze to death during cold winter months. People in a community helped each other as much as they could .. And charity (both giving and receiving) was a frequent routine. If you were sick ..
You still plowed your fields .. If you lost a limb, you still plowed your fields .. There was no such thing as workman's compensation or insurance to cover living expenses during an illness .. Back then, if you didn't grow it and harvest it you didn't eat.
In a colony If for example someone suffered an incapacitating injury, they would be required to something they 'could' do .. Everyone had a job and were expected to contribute in one way or another.
