Read the following context and answer the question.
Context: Once home we just ate some supper and then , at exactly 9:22 p.m. , yours truly escaped to the bed and slept solidly until 10:30 this morning . Luckily for me , since I made it to bed early , the sleep quota was easier to fill this time ; this also made me believe that , perhaps , I might be a little better physically . * fingers crossed * However , today I feel as if there was a fight which had a Mack truck involved and I lost ; I survived , which is saying a lot , but lost the fight itself .
Question: Why does the narrator feel like they might be better physically ?
Answer:


Because they were able to sleep soundly .
