It's good to hear you took the precautions you did and you're still kicking.
There was a time when we did our best to keep mom in her house and we (siblings and I) did the shopping for her, etc, but she's too ornery and would go shopping or whatnot on her own anyway. She got her shots thru a center that opened up at the local community college. It's all only at-risk, healthcare and education folks who are eligible at this point as far as I know.
She too was a smoker into her 60s, has HBP, etc. When you think about how many smoked back then.. Most adults really. Even I did from my late teens to maybe 30ish. Health risks aside, I dunno how people do it today given cigs are ~$12/pack, unless you have access to unregulated / un-taxed tobacco products. The smokers I know today get theirs through local native american reservation stores.
