If it's any consolation, I don't know ANYONE getting any younger!
Thirty-five years of serious road cycling with the world's biggest (and probably heaviest) head toasted my neck to the point my neck won't even tolerate the less-extreme mountain biking riding position and I can't enjoy much archery or bow-building either. Never being a very talented cyclist or archer anyway, nevertheless I hate(d) to give them up.
Have noticed that cocking powerful side-lever springers also aggravates my neck, but I'm not particularly drawn to them anyway. No problem with even very powerful break-barrels, though (thankfully, and I'm LOVING my new AA Pro Elite).
Even too much key-boarding bothers my neck. So I've learned to moderate the things that aggravate it, and consequently have much less problem with stiff-neck syndrome these days.
Thankfully the activity that caused the neck problem in the first place (decades of road cycling), (also) strengthened the rest of my body/constitution enough to not be suffering many other afflictions normally associated with old geezers my age.
Doctor Strangelove's advice? "If it hurts, STOP DOING IT!"
