It's not whataboutery though, it's a very simple reflection on the fact that many behaviours could be seen as a "strain on the NHS"
extreme sports, for example, a friend of mine likes extreme surfing, he injures himself regularly, should he be forbidden from surfing because he is putting pressure on the NHS? what about my ultramarathon running friend and her continuous stress fractures?
what about workaholics? stress is unhealthy.
It's just a really dangerous way of thinking that opens up all sorts of judgemental commentary at best, undue interference in people's behaviour or denial of care to certain categories at worse (if we started thinking that people who behave in certain ways should be made to pay for their care, for example)
health is such a complex combination of genetics and lifestyle that we should not be too quick to judge people in my opinion
but people love a good fat bashing session, no? nothing like feeling superior and righteous when compared to the lazy fatties, yeah?
