And the reason they have a job? "Political correctness". "Fat discrimination". It's the same argument, why should anyone want to pay for a fat Personal trainer?
If they didn't get a job, they would claim discrimination, the SJW would go mental and the council/company wouldn't have the spine to get people told.
Ultimately though, it will cost lives. Lifeguards need to be and should be held to high fitness standards. Same with public services (which are an absolute joke, in the name of "gender equality") and especially with the military, which is also a bit of a joke. And now they want to drag down standards for political correctness of women joining frontline combat units. (Another debate for another day).
Because we as society have become weak. Caring about feelings, over facts. We keep making excuses for people's lack of discipline.
Why can we not strive for mental and physical fitness? Socrates said that a mans body was a reflection of his mind.
But overall you are correct, the food that enters the mind is as important as the food that enters the body.
I beleive in freedom and liberty for all, so if people want to get fat, fair enough but don't expect the rest of us to bend the facts or be held down. For example the "Health at Every Size" pseudoscience that's now poisoning the youth.
When I left the regulars I hit a bit of a low, wrapped my bangers in with phys and it got to a point where I said enough was enough and dragged my fat ass back. I could recognise the damage I was doing and the shambles that was my fitness. I was walking round wit effectively a set of full webbing on. The damage on my joints, my heart, would have been incredible.
Ultimately it's up to the individual. Either suffer the pain of discipline, or suffer the pain of regret.
