Also if you live in America there is currently a WAVE of measles working it's way through Florida and various other parts of the county.
Measles is airborne and VERY contagious, and also the measles vaccine wears off after 12 years or so (rough estimate, I'm on mobile and can't double check).
Measles seriously effs up your immune system, it's in your best interests to NOT catch it.
Please wear a mask, for yourself and others.

You can restart Covid safe practices at any time! No matter when or why you stopped!" in red & pink capital letters. end image description.]
