I notice that many of you have mentioned balance problems. Me, too. Any idea how to improve in this area? I’ve been watching and practicing along with Qi Gong videos on YouTube. Not sure if that will help.
Tangentially related: after my bench was stolen from my front porch last week, I’ve installed a Wyze porch camera. I’m very satisfied with it! It was only $40-ish from amazon, and has a variety of settings and features.
But the first video I saw of myself walking up to the front door-- 
I look like an OLD LADY! Rounded slumped shoulders, shuffling walk-- who the fuck is that ancient, stumbling relic of a person?? NOT ME, FFS!
I’ve gotten used to seeing my blotchy face on Zoom with its broken blood vessels and brown spots, but seeing my whole self in motion was too much… 
Sigh.
Since then, I have made a point of holding my head up, shoulders back and relaxed, and striding instead of shuffling. Even though that posture feels completely unnatural, I can see the improvement in the videos.
