Chronic inflammation appears to be caused by persistent self-stimulation -- eating for comfort or pleasure, not getting enough sleep, chain-smoking, getting high, etc, without respite. So it's not really a biological problem. It's a widespread personal problem with complex biological consequences.
Even if chronic inflammation was caused by self-stimulation, that still makes it a biological problem. Maybe you meant it wasn't an inherent, biological part of aging? If that's what you meant, then I still don't agree. IMHO, the biggest contributor to chronic inflammation is the Standard American Diet (lots of grains and refined foods) combined with a lack of exercise. These things have a greater, compounding effect…
>lots of grains and refined foods
i.e. rather tasty! I don't think we can escape from motives here: they select what type of diet we prefer given the choice. The market caters to that.
