When I’m 64

Wondering everyone’s thoughts on this. At 64 I’m not sure how I’m supposed to feel physically. I’m healthy and thin. Exercise regularly but still never feel good? Hard to explain but just curious is anyone else is experiencing this. Thanks.

Thanks for all the responses. Honestly surprised at the engagement! Actually have my yearly physical today so we’ll see how that goes. And neglected to mention I’m male. Did also see an ENT yesterday for pain in right ear/upper throat. Have to get an MRI. Thinking maybe swollen lymph nodes.
