Energy Level

When I left work today, I had an errand to run, and then headed home.  I knew I had several chores to accomplish when I arrived home, and I was well braced to do them. I had lots of energy and attacked my tasks and chores with lots of energy early in the evening. I was concerned that this expenditure of energy would sap me later in the evening, and to some extent, that has happened, but it is still early and I can go to bed early. I used to not have to worry about my energy level to this extent, but a sign of aging is that I need to be aware of this.
