Wow.
   FORTUNE EXCLUSIVE: The world's second richest man - who's now worth $44 billion - tells editor-at-large Carol Loomis he will start giving away 85% of his wealth in July - most of it to the Bill & Melinda Gates Foundation.
    
  I know I seem to be pretty much animal focused in my thinking and concerns, but I do let the people news sink in from time to time.  I recently read a 
Time (or was it 
Newsweek?) article about the 
Bill & Melinda Gates Foundation and was absolutely in awe of what they have accomplished.  They have proven that, if you're filthy rich and 
want to make a difference for good, you can.  Pretty impressive.
