and to actually think there will be a LOT more of this as cost of living and shit healthcare increases 
Someone I know (builder in his early 60's) has had 3 operations in last 3 years - two hips/one knee (and needs the other knee done) - they have cost him £22,000
but of course he couldn't get an appointment for the first one (Covid) and the last 2 they said he'd have to wait 5-6 years!
He couldn't work unless he had them done - as it is he had to take off 8-14 weeks for each and they told him he'd be retired before he even had them done
They were (obviously) not getting any better as they're degenerative
If he hadn't had them done he'd have had to give up work and there would be no tax collected at all
The way I see it he will now pay tax for the next 6-10 years and frankly the government got a good deal
(In case anyone doesn't know how self employed tax payments work he essentially declared an income - say 30k as he was off work a lot and then deducted the cost of his surgery from that - and pay tax on the balance)
