A man loves tractors

There was a man who loves tractors, he had hundreds of model tractors, had a job maintaining and fixing tractors, and owned many tractors himself. He also had a wife, and like him, she loved tractors, together they were very happy with each other and their tractors.
One day the couple were driving along the road when they passed a big farm delivery truck carrying tractors when one rolled off the delivery truck and hit their car. The wife had to be hospitalized due to her injuries.
The man visited her in hospital, and she was on her death bed when she said to him, "It's not the tractors fault, don't hate the tractors" and then she passed away.
The man was distraught at the loss of his wife and his sadness eventually turned into anger, which he directed at tractors. He burned and destroyed all of his models, sold his own tractors and quit his job fixing tractors before moving to a new city, where he met a woman and together they went to dinner.
Inside the restaurant it was very smokey, because lots of people were smoking cigarettes, it was so smokey they both found it a little bit difficult to breathe. The man decides he has to do something about this, so he breaths in 3 enormous lungfuls of air, before running outside and letting all the smoke out then he sits back down with the woman in the restaurant and she asks" How did you do that!?" and he replies, "I'm an ex tractor fan".
