From: Corina Tamita To: Jeffrey Epstein <[email protected]> Subject: Re: Date: Sat, 21 Nov 2009 17:22:18 +0000 i see your point. i'll look more into signal-to-noise. i have to learn a bit about its use in cell signaling.

His maxim of " Know thyself " , might let predators also know you , and destroy or hijack you with less effort.
