No worries. We're older and often cranky from the aches and pains that go along with "life's experiences". It's not unusual for those factors to influence our posting styles occasionally.
FWIW, I was a long time mod on a couple other niche interest websites, starting when I was in my late 30s back in the 1990s. I noticed my own posting style changed after a car wreck in 2001 busted up my back and neck. On days when I was in pain I tended to be a bit curt and occasionally belabored debates to the point of gratuitous arguments.
By 2014 or so I realized I needed to make some changes. I was just as grumpy and occasionally rude as some of the folks I was supposed to be reining in. Not a good characteristic for a mod. So I quit and took up bicycling again.
Best thing I could have done for my overall well being.
But, yeah, as we've discussed in some recent posts, occasionally it's frustrating when the body doesn't cooperate with the mind's determination.
When I have days like that I step away from the keyboard and put the pressure on the pedals, or just walk more. I don't walk nearly enough now and it works different muscles -- although it's never as enjoyable as bicycling.
