Who is happy?Psychology experts have been fond of stating in recent years that human happiness, or what psychology experts call subjective well-being, is largely independent of our life circumstances. The wealthy arent much happier than the middle class, married people arent much happier than single people, healthy people arent much happier than sick people, and so on.
One might reasonably conclude, therefore, that changes in life circumstances would not........Go to the Psychology news blog (Added on 3/6/2007 4:57:05 AM)

MMR, chicken pox vaccines work for preemiesVaccines for measles-mumps-rubella and varicella, or chicken pox, are effective in extremely preterm infants, even though preemies' immune systems are not as developed as full-term babies.
