credit where credit is due

Is anyone else tired? I can’t tell if it’s a function of the my workouts, but I’ve been tired for the last week or so. It’s not from a lack of sleep, because I have never gotten any of that. It’s not from anticipation, stress or anxiousness, because the world doesn’t bother me much. Maybe it’s a lack of fuel, or too much of the wrong kind. I don’t think it’s a blood disorder, nor do I think it’s from thinking too much. It’s certainly not from boredom. Perhaps it’s from the time of year. I think I’ll just blame it on the weather.
