Tired

I am soooo tired. I'm trying to edit papers I've written to submit for publication (which is taking a fair amount of thought), I'm collating data from my current project and trying to keep on top of tissue processing and analysis, I'm reading part of a PhD student's thesis, and I'm keeping my BSc student nice and busy. On top of that I've almost finished putting a prospectus together for a client in my other job. I need to learn how to survive on 4 hours sleep a night. Possible?

My iPod is keeping me happy!
