Recommended use of abusive words

My father was probably born with running shoes. He has spent most of his life doing sport when not at work. He used to run an average of 1'800 km per year and ride his bicycle around 10'000 km per year, plus countless km Nordic-skiing and rowing.

He used his body till its limits and beyond, and his joints paid the biggest price. He can now barely walk as his kneecaps are too thin. Doctors told him to slow down 10 years ago, when he was 70, but he laughed at them and kept going.

Last month his heart said enough and started going into fibrillation several times a day. He spent 5 days in hospital and got medications that never took before. After less than 1 week out of hospital he unilaterally cut his pills to half and took a 2-hours ride on the bicycle. Then another ride the following day.

And then I had to take him to the ER. The nurse told him she would beat him if he ever got back there for the same thing. He smiled and thanked her, and the day after was back on the bicycle.

Two days later I was able to drag him to the cardiologist, who did something amazing. He abused my father like no one ever before. He spent almost half an hour of his precious time telling my father all the insults that I know of, while explaining to him exactly what could happen to him if he kept riding the bicycle and refused to take his medications.

He was VERY persuasive.

Now my father is sitting on a chair watching Giro d'Italia (an annual bicycle race around Italy) and taking all his pills on time. He's disgruntled. But he's alive and hopefully healing.

His heart is thanking the cardiologist. Me too.

Good manners are a must, we all agree on this. However sometimes we need to take a slightly different path to get to the desired results, and in this particular case I agree with the doctor's use of creative language.

I'm interested in your thoughts, opinions and particular cases :)
