The problem with this, is where does it stop? Should a smoker be lower down on the list of cancer treatments? We’ve known for several decades the dangers associated with it. Same for skin cancer, should a person who has enjoyed many foreign holidays, thus exposing themselves to sun damage, be told no, while the person who chose to avoid the sun gets treated?
My dil recently suffered pregnancy complications (thankfully fully resolved). She’s fit, active and a healthy weight. By coincidence, my niece had a very similar problem. She is considerably overweight, should she have been turned away, because there is an argument that her ‘choices’ hugely impacted her health.
Would you want to be sitting in A&E and have a doctor decide between you, and the person next to you based on their own moral code? To be told that unfortunately you wouldn’t be permitted a bed. They’ve compared you with another patient and, while you have enjoyed a croissant on a Sunday morning, they’ve followed a low fat, low sugar diet. They do more exercise than you, and so their ‘choices’ have made them more deserving of a bed? It may sound extreme, but I fear that what you’re suggesting would be the start of a slippery slope.
