5x5 DL LinProg or "Why Can I Hear My Heartbeat in My Head?" Workout

Lying on my living room floor, enjoying looking up at my ceiling fan and hearing the beep of the smoke detectors. This wod kicked my ass. I'm attempting some semblance of linear progression on my deadlifts. So I went up by six pounds on each set of five. Except it's now occurring to me that maybe I was supposed to do the same weight on all 5 sets of 5? Must ask husband later, who looooves linear progression so much he wants to marry it and have little linear progression babies with it.

5x5 Deadlift
95, 106, 117, 128, 139

I finished the 128 lb set of five and stood up. Then I became very aware of how much blood was whooshing around in my head and realized that I could hear my heartbeat. So I walked around and literally tried to shake the blood out of my head. In retrospect, I probably should have just sat back down. Do PRs count if you pass out after? It probably shouldn't. At Nathan's Hot Dog Eating Contest, you're disqualified if you throw up afterwards. Isn't that almost the same thing?

PIC of the day: This has nothing to do with Crossfit, I just think it's funny.
