7,8-Dihydroxyflavone 

7,8-dihydroxyflavone (Tropoflavin) is a supplement that is an antioxidant. It has also been found to act as a potent and selective small-molecule agonist of the tropomyosin receptor kinase B (TrkB), the main signaling receptor of the neurotrophin brain-derived neurotrophic factor (BDNF). In addition, tropoflavin possesses powerful antioxidant activity independent of its actions on the TrkB receptor, and protects against glutamate-induced excitotoxicity, 6-hydroxydopamine-induced dopaminergic neurotoxicity,28 and oxidative stress-induced genotoxicity. It was also found to block methamphetamine-induced dopaminergic neurotoxicity, an effect which, in contrast to the preceding, was found to be TrkB-dependent. 7,8-dihydroxyflavone protects against stimulant induced glutamate exitotoxicity and dopaminergic neurotoxicity. By stacking amphetamine or other stimulants with Tropoflavin, you can prevent brain damage. However, you can't prevent cardiotoxicity. So choose a less cardiotoxic stimulant like amphetamine, Ritalin, caffeine, or EthylAmphetamine, or Modafinil, the wakefulness enhancer, instead of choosing more cardiotoxic stimulants like crack. Crack is wack, speed(amphetamine, EthylAmphetamine) will help me succeed
I stacked 25mg EthylAmphetamine with 25mg 7,8-Dihydroxyflavone and I prevented brain damage. Tropoflavin is awesome!

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
