Are there really 24 hours in a day

Where does my time go. I wake up and I write for thirty minutes to and hour, I then walk a mile and a half on the treadmill, then I organize my day to get things accomplished, then when I have a chance to sit down I write another thirty minutes to an hour then stop to read emails on what others are doing the write some more. Then it is time for bed and I wonder where my day has gone. I seem to have had more time when I was working to get things accomplished than I do now. I am making it a point to start to read again I miss my friends that come alive in stories by Mercedes Lackey, RA Salvatore and Catherine Asaro.
