Don't your telomeres get shorter, your DNA gets damaged and it doesn't replicate correctly anymore? Some animals can be immortal like lobsters but face limits like their physical size can kill them when they molt enough.

I think the consensus is that it’s part of the process, but not the whole picture, but I’m no expert.

Yes, that's one of around 50 currently recognized factors of aging.

This isn't comprehensive, though. I don't see intracellular or extracellular waste accumulation, for instance.

I'm not sure if this is one of the consensus primary causes but the most compelling explanation I've heard is capillary damage.
Red blood cells and capillaries have roughly the same diameter leading to constant friction. Your body repairs the capillaries but, given enough time, it makes mistakes. As these mistakes pile up your circulatory system, your body's supply chain, slowly gets less efficient. This leads to every cell in your body gets the energy it needs a little later, and has to hold onto waste for a little longer.

If aging was just DNA errors, wouldn't it be far less consistent in how it effected people?
