Our bodies work like our small businesses. They work best by word of mouth, networks, referrals, etc. The Internet also works this way to serve the most good thru networks, portals and referral links; of course the Internet could work better, but all in all we are well served by using such systems and we are most hurt when those systems are used against us. For instance a virus in the blood stream, an International Terrorist in an airliner, a drug dealer in your neighborhood or a computer virus .
