Lead may make a person stupid and eventually kill him, but there is no evidence it makes anyone violent or crime-minded. Further, there is no really good correlation between leaded gasoline and blood levels of lead! Aviation gasoline still contains lead, and in colossal amounts-such that one pint of avgas in 10 gallons of unleaded car gas will boost octane ratings five or more points. Are people working around piston-engine aircraft generally rendered stupid? |
