["I'm really said. I'm missing my youthful vigor."]
Your youthful vigor? You think you're too old now? You're only too old if you allow yourself to be. My girlfriend's 90-year-old grandfather was a full-of-life WWII vet who lit up the room when he came in. Of course, you're not as physically active, but you have to learn to utilize your life in different ways.
I miss my childhood.
