Eh... I know this is a meme sub, but this undermines any arguments to be made about real problems with healthcare systems by just... not being accurate.
If you need stitches in the UK, that's an A&E (ER for my North American friends) sort of ordeal, and yeah, you won't be seen immediately because the system is badly managed and overwhelmed. You'll have to wait several hours (unless you're bleeding out/at risk of death, in which case you'll be seen quickly), not 43 months ffs.
That said, anything that's non-urgent can take a few months. The only exceptions to this are 1) mental health, where you're looking at several months for the waitlist almost irrespective of severity, and 2) gender-affirming care, where you won't be seen for well in excess of 5 years, which at this rate & in this political climate (TERF island), is likely to outlast the NHS gender clinics themselves. Private is still an option for both of these branches of healthcare, but it's expensive for sure.
