I just turned 70. I have the mental energy of a 40-year-old but the body and physical energy of a 60-year-old. I'm not sure what I'm supposed to feel like at 70, so I continue to do what I've always done. The only difference is that I've reduced my risk exposure. I increased my rest times, modified my diet, reduced alcohol, and see my doctors for regularly scheduled wellness exams. Life is good. Thanks for sharing your perspective.
