I have two injured vertebrae in my neck from sitting at a light in my Alfa years ago and watching in my mirror as a guy drove into the back of me.
When it is inflamed, I can't write.
Though it is expected to deteriorate, I haven't had any kind of therapy on it in 15+ years - good circulation from bicycling (properly) is mostly what I need.


When I bicycle I adjust my helmet mirror so if I'm lifting my shoulders it blocks my view and I immediately relax my shoulders, which also gives me that burst of spin energy.
