A little known secret to on track speed is having just the right amount of helmet "stank".
What is helmet stank, you ask?
Well, take your helmet and put it through a few heat/sweat cycles. Then put it away without scrubbing it out. Repeat as necessary.
Once it reaches a point where it smells like an opossum deficated, died and was then lit on fire in it, you have achieved the state of "stank".
Now, once you slap that brain bucket on your noggin, the fumes will begin to soak in just about at the green flag.
By the first corner, you cannot help but go as fast as possible just to get the thing off your dome where you can then liberally douse it with Raid, Lysol, and perhaps some Oxy-clean.
