I have been writing LOTS of content for a project in the past months and they're mainly on finance and medicine. Most of the time, the titles are the form of What Is [INSERT TERM HERE]? Let me tell you - I have learned more about finance and medicine in the past two months than I have ever learned during a semester of economics and biology!
Then again, experiencing insomnia first hand is never a fun thing. Sure, it may be informative in the experiential way, but this is one case wherein I'd rather experience things vicariously.
They say that insomnia has various causes, some of which may be physiological while others are psychological. They say that oftentimes, insomnia is caused by emotional and/or mental issues that you are unable to resolve. No shit, Sherlock!
Seriously, though, insomnia has been bugging me on and off for as long as I can remember. Nothing has changed there. It's just a matter of when it will start again. For now, it has started, and I cannot do anything but at least get more work done while waiting for my eyelids to close on their own. Either that or fly away to some isolated beach and feel everything melt away. That's always the best cure. Don't let anyone tell you otherwise.
So what's insomnia? Check WiseGeek. ;)
