🕶️ Hi Steve. I’ve been following Covid closely since the lockdown days, spending several hours each day doing the research here in Australia. In respect to your new glaucoma post, I wrote to you many years ago on the subject. As I’m in the same position as yourself but don’t wish to pay for a Substack subscription, if you could make your latest post on glaucoma free I would be most grateful. Kind regards, David W.
