Occupation

What about my response?

To those with some medical background, let me tell you this:

Occupational dust exposure is an important cause of lung fibrosis.

No, not everyone with an exposure would end up with such a problem; the vast majority tolerate and do well. Some actually develop a different lung problem (say, occupational asthma), which could even be more common than, but not as dramatic as, lung fibrosis. On the other side of the coin, not all cases of lung fibrosis are caused by occupational dust exposure. (For example, there is something called cryptogenic fibrosing alveolitis.) Nonetheless, in real life, a good proportion of patients with lung fibrosis are caused by occupational dust exposure - and they have characteristic features.

And, all the points mentioned above are not reasons for not improving the working environment and minimize dust exposure.

Same for occupational brain disease.
