Meanwhile, fat people, drinkers, smokers, self inflicted diabetics, sexually promiscuous, drug users, risky recreational hobbies / activities / sports / drivers etc
Your posts screams ignorance and victim blaming. 'Self inflicted' diabetes? Hmmm. Stress, poverty, and genetic disposition. Nope. None of these tend to be self inflicted.
Overweight people. So the majority of the UK population (around 60% are overweight).
The number of overweight people has increased since the decline in smoking...
Smokers have paid for their NHS treatment and then some. Studies have demonstrated that smokers are a net economic gain. High tax income and lower pension and social care costs.
Obesity, smoking, drinking, drug taking, other 'self inflicted' issues. For thousands of years humans have turned to various substances (eg. sugar, narcotics, herbs, alcohol) or solace and respite from misery, poverty, and (emotional or physical) pain.
There are also many medications (including some used to treat mental ill health) plus medical conditions that cause weight gain.
Add in long NHS waits (going back years before the pandemic) for diagnosis and treatment - leaving many languishing in pain or with limited mobility.
