In the UK, I've not worn a mask since the Corona scam kicked. Masks are for bed wetters, retards and virtue-signalling spunk junkets.
When the government (pig snouts in the trough) stated the fine for refusing to wear a mask rose to £200, I researched their own website and found that a sovereign individual can exempt themselves and don't even need to provide any ID for this from the GOVERNMENTS OWN TEMPLATES.
There's no need to consult a doctor, and if anyone asks what your medical condition is, that's illegal to ask and is private and confidential information.
If you're wearing your mask (along with your pink vagina hat, black lives matter T-shirt and Extinction Rebellion flag) you're either a pussy and/or ignorant.
