Thus begins the period of sleep deficits

Ah, that lovely time of year has arrived. No, I am not soley referring to daylight's savings time. I am referring to the phase of graduate student life that happens about 45 days before the end of the term, marking significant drops in the hours of enjoyable sleeping.

Sleep. It's so nice. And you really appreciate it when you only get about 4 hours of it a night. Allowing my body to rest horizontally, which scientists have determined should occupy about 30% of typical day, has started to become an irregular practice. I would guess I only spend about 14-17.5% of my day sleeping. The remaining 85% or so of the day is broken down as such: 15% standing and walking (showering, in line to buy coffee, getting between classes, perusing library book shelves), 3% cycling to and from school - leaving approximately 67% of my day sitting upright in a chair. Just like I am doing now.

I can actually feel my circulation being compromised. What's scary is that the worst of this cycle has yet to begin. Last night I was up until 3:16 a.m. And what do I have to show for it? Sadly, just some downloaded pdf's I found on Google Scholar.
