Dear Luke,
As you know, I read, search, and ask lots of questions of people. This has been my job for 20 years. Everyday I learn something new and in the computer industry are required to learn new stuff all the time. You never stop learning...
So, I learned about your illness (chronic fatigue syndrome) also know as CFS. I learned that you need to (as much as it pains you) using that drive, I know you have, to get up and do some exercising to help you sleep at night. Also, you need to get some vitiman D ("sun light"). These two things like when you were a little boy help you to fight off viruses and can get you back on your feet. I sure miss that energy (you remember when I used to race you around the house, you always beat me!).
Dig deep Luke and fight this crap!
Love ya,
Dad
