Ch7 says, Using trains and busses are 'bad for your health'

On the 'Morning Show' today (Monday Ch7) they had stated a study had been released of which said something along the lines that, those of whom use public transport (busses and trains), experience a very unhealthy and unsafe environment.

Problems put out by this study are,
++People experience 'loss of control' of where they are 'not in control in what is going on around them'
++People experience Heart pulpertations

I did not get all of the items of which they had stated.
And other safety and health problems like them.

My views are,

What is the problem with these people who feel they may die due to experiencing these problems?

The way in which the Ch7 report went, was clearly way over the top, and Ch7 made it sound a lot worse than what it is.
