Voltage, like batteries, not required. I meant belief in the future. The sun will shine tomorrow. The robotic fact that we have to go to work, take care of our children (bless them),pay bills, go swimming, no matter how mundane it is, or how important, these are the survival rituals that gets us through.And darn if slowly one doesn't start feelin better......
And not for nothin but livin well is the best revenge
