Colds and Flu

My husband is getting over his flu he got from his flu shot, but he is pretty weak yet. He walks on our Gazelle for 15 minutes, twice a day, but he found he couldn't make it very long this morning. And now he's got a cold. I don't know where that came from but he is coughing and runny nose and the works. I need to get to the store later and get more tylenol too. It helps with the aches and pains. I put sheet blankets on the bed this morning. That should make it warmer but he uses the electric blanket all the time now too. I think we are about due to get another new electric blanket.
