Again, my post is all about overestimating risk solely based on age. This is the only issue I had here. Also, just because someone doesn't have comorbidity listed on paper and is not taking prescription drugs to manage them, it doesn't mean that the person is healthy. There are lots of people who never go to a doctor or take any prescription meds, even though they have some ongoing health issues or diseases present. If you are not looking for something, you won't find it. If you have something, some health issue, but it isn't manifesting itself in a sufficient manner to really bother you, you won't get tested and treated. This is one of the many examples where your math and assumptions can be flawed, can mislead you, and you won't be able to spot this. Just because someone appears to be healthy on paper, it doesn't mean the person is healthy or doesn't have issues that impact their immune function and diseases susceptibility. There are lots of people living in suboptimal health, and they never know it, they are just getting used to how they perform and feel in their day-to-day lives. Senescence's role is once again being overestimated here because you can't see the big picture. This is what happens when people operate from a false premise, and they don't even know it. Aging is real, no one is questioning that. Over time, the body becomes less efficient, accumulates wear and tear, requires better maintenance, higher quality nutrition for proper function, etc. The only issue here is that people overestimate its role and impact, which later leads to false statements and assumptions, as presented here.
