I think I can explain the phenomenon of why people don't always do what is healthy. Most of what is healthy involves either giving up something we enjoy, or doing something we hate. Think about this! Would I rather excersize until I get all sweaty and everything hurts, which will make me feel better..in a few weeks..or eat a large chocolate bar with almonds, which will make me feel better right now, and maybe in a few weeks I'll be in an emergency room clutching my fat blocked heart, or MAYBE, I'll be out looking for more chocolate, the white kind, that rots my teeth before I even take it out of the wrapper...... Life is so uncertain, but enough fat, chocolate-loving folks can ensure that we'll never see a heart surgeon on welfare!
