Is this a reasonable excuse to have never worked a day?

A 52 year old man I used to be related to was born with a hole in his heart. When he was in his late twenties and had children he decided to go to Court Reporter School then dropped out. His mother was told it was a very dangerous condition so she accepted it as did his wife. He took up drinking in his forties when his wife left him for a man who is employed and he had just had surgery to close the hole . Now he’s fifty two, living with his mother and drinking daily. A friend of mine had her hole sewn up in her sixties and she’s fine. Do you think this man should still be sponging off his 80 year old mother?
