Actually, I am very sleepy. Was at work till last night/this morning, and got back to work around . But when you think about it, this is precisely what college prepared me for: long nights and sleep deprivation. So it's all good...I went to a very good college!
When you exercise, however, it turns out that your brain is what makes you feel tired, as opposed to your muscles. The hormone Interleukin 6 (IL6) was elevated in athletes after a big workout, and injecting them with it made them feel tired. So just like Coach said: it's all in you head!
