Holy crap! Can someone get this stuff out of my head. I can't stop thinking about boundary layer maintenance over weld seams in exhaust headers. I love this stuff but sometimes I really need to shut it off.
Same thing goes for the battle of Leige at the start of WWI. Being in a quandary about which historian to believe has me up 4:30 AM comparing sources.
I've really got to do something about this collection of facts swirling around in my head. Perhaps on the other side of that "doing" I can get get an 8 hour sleep in!
