When you're an addict, you can go without feeling anything except drunk or stoned or hungry. Still, when you compare this to other feelings, to sadness, anger, fear, worry, despair, and depression, well, an addiction no longer looks so bad. It looks like a very viable option.

A child allows us to revisit the excitement we once felt about, well... everything. A generation later, our grandkids bump up our enthusiasm yet again. Reproducing is a kind of booster shot to keep us loving life.
