Sorry to hear about your health sir.
I think the odds are your speakers will be fine. I’ve had multiple 30 year old speakers and none of them had issues.
my upstairs system is a 50yo Sansui, 30 yo Krell and 30yo Paradigms. Sounds great. Preventative maintenance would be keep them out of the sun and in a semi climate controlled environment. Other than that you’re probably good 👍.
