Memory depends on connections created by your brain throughout your life. Try recalling an event from the old pictures and then ponder on it - the chain-reaction effect should activate and the more items about that event you recall the more will be uncovered by what you can already remember. Put it simply - one leads to another. You activate electrical reactions in your brain and it creates webs of "forgotten" information. Most leading memory development resources are based on harnessing the connections principle.
As far as the Liver Flush goes then it almost goes without saying that healthy organs (especially liver) facilitate healthy blood flow which in turn will bring about not only a better ability to recall things but your level of overall hapiness as well. I've done several colon cleansings before i did my Liver Flushes and that alone changed the way i think and feel about my life in a very dramatic way.
