Good points made via the Life Extension Foundation News: "The concept of 'old age' doesn't have much use when you're trying to get well. Almost all aches and ailments can be traced back to pathology - something that has gone wrong with the body, a disease. Once we have identified a disease, we know where we stand, and frequently we can offer a treatment. So attributing a problem to 'old age' doesn't help us solve it. But when we try to understand certain situations, particularly where an aged person is very ill, the idea of 'old age' starts to have some value. There is a feature of aging that we cannot attribute to a single pathology, and that feature is a buildup of multiple pathologies that won't get better, and which tend to worsen each other." There's no such thing as normal age-related degeneration; none of it should be normal, and we can effectively work towards addressing the root causes of all of it.
