Fingers crossed! Certainly much more will be known about human biology and the mechanics of aging by then, given that what we know currently is mostly so recent (it's instructive to remember that the two of the guys remembered for discovering the nature of DNA, Watson and Crick, are still alive, and the latter is still an active researcher [1]. Molecular biology is that new.) But- all your examples suppose not only advances in biomedical science, but also medical care aimed at correcting each of these problems. It adds up to a lot of drugs, therapies, or other interventions. In today's system, a well-off and health-conscious individual would receive that level of care as a matter of course- but today's system is a sprawling and highly dysfunctional apparatus already, and I don't feel entirely confident about how it will change in the face of future economic upheavals, political madness, climate-change-fueled social instability, etc etc etc. The lifespan of humans is increasing, but the lifespan of social infrastructure such a the medical industry may be decreasing... which is especially problematic since the former depends on the latter.
