A lateral flow test or something using a lab?

Must be a lab test as lateral flow is like £2.

Or $7 in Walmart https://www.walmart.com/ip/Flowflex-Covid-19-Antigen-Home-Test-1-Test/837992467?classType=VARIANT&athbdg=L1200

I WFH, so my chair gets a lot of use - it’s one of the tools I use.

If I was an electrician, or I commuted to work I know I’d be paying for tools, fuel, repairs, train tickets etc

I don’t know what your circumstances are, but I find a cheap chair falls apart pretty quick.

The better office chairs have 10+ year warranties, if you spread out the cost of buying a cheap chair (£150) every 2 years Vs a £1000 one that lasts 10 years its not such a huge difference in price whilst the benefits to your back are worth much more.

I know not everyone can afford this, but it’s worth checking for interest free credit from either the manufacturer, store, or even PayPal / klarna (which is what I did).

Left 4 dead 1 & 2.
Back 4 blood.

And don’t forget to update us on the outcome!

Haha after an all night session back when I was in high school I did the very same upon hearing a tractor in a field nearby.
