Let me be blunt—you are not getting away from posting pictures. Any excuse is a bad excuse.
Your work is too inspirational to leave to mere mortals. Chris, you will always be one of us.
Every so often I get the itch to get some M43 gear just to play around - so many of those M43 primes are so petite!Get well.
I actually moved from Nikon to m4/3 for personal stuff several years ago. I really like the smaller system and for most of what I shoot now, the convenience of the smaller system out weighs the advantages for me. When I stopped shooting events I did sell off all my Nikon gear.
I will admit I do like what I've seen in the Z system and I have considered it. But they need a few more lenses first, most are on the roadmap, so time will tell.
Sorry to hear you are having to go through all of that.
Good luck with your cancer journey I am about a year and a half into mine (stage 3 clear cell renal carcinoma that spread to lungs and kidney).
