Question - You are working a full-time job. You started taking classes at a community college about 30 minutes away for your associate's degree. You're sweet little daughter has begun cutting teeth and crying a lot more, including bedtime. To top it off... your best friend has convinced you that running a 10k is a good idea and that you need to start practicing by running around town instead of your treadmill. To say the least, you are so tired. Sleep is very limited. Can someone help me explain? What happens to your body when you start losing sleep? How will it affect you physically and mentally?
