Tier standards for diesel engines won't help my brother who for 25 years was a heavy equipment operator. Now, his lungs look like he was a coal miner, black lung.
I operated diesel tractors as a kid. To this day I can't stand to get close to a diesel without getting a headache instantly. My headaches have been going on for decades. It only takes a few seconds for them to occure. I'm healthy, just had a stress test, good heart. No medical problems the doctors know of.
I know diesels are necessary for large trucks and tractors.
If I were in charge diesels would have to clean up their act so I don't get a headache. I have to stay at least a 1/4 mile behind any smelly diesel.
I hate it when pickups have to show off and blow black smoke in town next to me.
wonder how long this post will last?
