My mind is Troubled

How possible is it that diseases & illnesses no ur age or ur body age. If u listen to commercials they always say if u r 45, 50, or 60 (wateva) age, u need to get shots or take wateva drugs they r selling. So once you hit that age ur body automatically acceptable to wateva disease or illnesses (viruses). Hv anyone else that about this or does the government think everyone is ignorant.

Think about it, when CoVid came out they said 5 & above needed to get the shot & CoVid is a respiratory problem. So if u were 5 & below u didn't breathe. DUH!!!!! Is it me or hv anyone else thought about this
