Aeon is an assassin from shadowy Monica, Trevor...
- what's with Italian city names?

Why are some things like Richter and Decibel measured in a non-linear scale? What benefit is there?

Why do FM radio stations only end in odd decimals?

The power of the Tobacco industry and do they have the power to completely halt the legalization of marijuana for recreational use in the United States?
Pretty much everyone I know who smokes marijuana smokes it with tobacco so I'm not so convinced they will be hurt that much by it's legalisation.
