When The Who brought forth their great youthful anthem, they were railing against an attitude rather than a natural order. The good news is that very little of one's attitude need be driven by age. We need not become those stodgy old characters, pining for the old days and criticizing the new. Similarly, we need not passively accept age-related degradation. While nobody has the same physical potential at 50 that they did at 20, the slide need not be quite so steep, and other aspects of age can help compensate. Truly getting in tune with one's body takes years and that understanding can be invaluable. Developing mental stability and the ability to pace one's self can lead to greater overall performance. Above all, it takes most of us quite some time to settle into our own skin, and only then can we reach our own potential.
