There's a huge difference between endangering other people vs endangering only yourself.

[eloisant]

The carpenter isn't endangering himself, he's being endangered by his employer (and the politicians who voted for that retirement age)

[8fingerlouie]

Yeah, it's not like operating heavy equipment at a construction site will ever endanger anyone.

[stevenhuang]

Yes, doing so at a construction site it is considerably less dangerous to society in general than public roads. Not to mention the individual is more likely implied to be operating at some baseline of function (observed by foreman and others at the work site) which is not the case when a private individual is just driving on public roads.

You are straining credulity.

you've clearly never been fallen upon by a septuagenarian roofer
