Given reasonable luck, most people are OK until they are around 60-ish or so. From then onwards, it is anybodys guess, but at some point, jobs will take longer and energy decrease. Everything gets heavier, and small parts shrink in size (or appear to). In your specific case, you might be fine until you are much older, but that is unknown, so for things that require energy etc, doing them as early as possible makes sense.
